American and British English spelling differences

"Spelling differences" redirects here. For other uses, see Category:Language comparison.

One of the ways in which American English and British English differ is in spelling.

Historical origins

American medical text from 1814 showing the British English spellings still used at the time, such as "tumours", "colour", and "centres".

In the early 18th century, English spelling was not standardised. Differences became noticeable after the publishing of influential dictionaries. Today's British English spellings follow, for the most part, those of Samuel Johnson's A Dictionary of the English Language (1755), whereas many American English spellings follow Noah Webster's An American Dictionary of the English Language (1828).

Webster was a strong proponent of English spelling reform for reasons both philological and nationalistic. Many spelling changes proposed in the United States by Webster himself, and in the early 20th century by the Simplified Spelling Board, never caught on. Among the spelling reform supporters in England, the influence of those who preferred the Norman (or Anglo-French) spellings of words proved to be decisive. Later spelling adjustments in the United Kingdom had little effect on today's American spellings and vice-versa. In many cases, American English strayed in the 19th century from mainstream British spelling, but it has also kept some older spellings.

The spelling systems of most Commonwealth countries and Ireland, for the most part, closely resemble the British system. In Canada, the spelling system can be said to follow both British and American forms, and Canadians are somewhat more tolerant of foreign spellings when compared to other English-speaking nationalities. Australian spelling has also strayed somewhat from British spelling, with some American spellings incorporated as standard.

Latin-derived spellings

-our, -or

Most words ending in an unstressed -our in British English (e.g. [colour, flavour, harbour, honour, humour, labour, neighbour, rumour] Error: {{Lang}}: text has italic markup (help)) end in -or in American English (cf. [color, flavor, harbor, honor, humor, labor, neighbor, rumor] Error: {{Lang}}: text has italic markup (help)). Wherever the vowel is unreduced in pronunciation, this does not occur: e.g. contour, velour, paramour and troubadour are spelt thus the same everywhere.

Most words of this kind come from Latin non-agent nouns having nominative -or. These words were first borrowed into English from early Old French and the ending was spelt -or or -ur. After the Norman conquest of England, the ending became -our in Anglo-French in a bid to represent the Old French pronunciation, though color has sometimes been used in English since the 15th century. The -our ending was not only used in English borrowings from Anglo-French, but was also applied to the earlier borrowings that had used -or. After the Renaissance, new borrowings from Latin were taken up with their original -or ending and many words once ending in -our (for example, chancellour and governour) went back to -or. Many words of the -our/or group do not have a Latin counterpart; for example, armo(u)r, behavio(u)r, harbo(u)r, neighbo(u)r; also arbo(u)r meaning "shelter", though senses "tree" and "tool" are always arbor, a false cognate of the other word. Some 16th- and early 17th-century British scholars indeed insisted that -or be used for words from Latin (e.g. color) and -our for French loans; but in many cases the etymology was not clear, and therefore some scholars advocated -or only and others -our only.

Webster's 1828 dictionary had only -or and is given much of the credit for the adoption of this form in the United States. By contrast, Johnson's 1755 dictionary used the -our spelling for all words still so spelt in Britain (like colour), and for words where the u has since been dropped: ambassadour, emperour, governour, perturbatour, inferiour, superiour; errour, horrour, mirrour, tenour, terrour, tremour. Johnson, unlike Webster, was not an advocate of spelling reform, but chose the spelling best-derived, as he saw it, from among the variations in his sources. He preferred French over Latin spellings because, as he put it, "the French generally supplied us". English speakers who moved to America took these habits with them and H. L. Mencken notes that "honor appears in the United States Declaration of Independence, but it seems to have got there rather by accident than by design. In Jefferson's original draft it is spelt honour." In Britain, examples of [color, flavor, behavior, harbor and neighbor] Error: {{Lang}}: text has italic markup (help) barely appear in Old Bailey court records from the 17th and 18th century, whereas examples of their -our counterparts are numbered in thousands. One notable exception is honor. Honor and honour were equally frequent in Britain until the 17th century; Honor still is, in the UK, the usual spelling as a person's name.

Derivatives and inflected forms

In derivatives and inflected forms of the -our/or words, British usage depends on the nature of the suffix used. The u is kept before English suffixes that are freely attachable to English words (for example in [neighbourhood, humourless and savoury] Error: {{Lang}}: text has italic markup (help)) and suffixes of Greek or Latin origin that have been naturalised (for example in [favourite, honourable and behaviourism] Error: {{Lang}}: text has italic markup (help)). However, before Latin suffixes that are not freely attachable to English words, the u:

• may be dropped, for example in honorary, honorific, honorist, vigorous, humorous, laborious and invigorate;
• may be either dropped or kept, for example in colo(u)ration and colo(u)rise); or
• may be kept, for example in colourist.

In American usage, derivatives and inflected forms are built by simply adding the suffix in all cases (for example, favorite, savory etc.) since the u is absent to begin with.

Exceptions

American usage, in most cases, keeps the u in the word glamour, which comes from Scots, not Latin or French. Glamor is sometimes used in imitation of the spelling reform of other -our words to -or. Nevertheless, the adjective glamorous often drops the first "u". Saviour is a somewhat common variant of savior in the US. The British spelling is very common for honour (and favour) in the formal language of wedding invitations in the US. The name of the [[[Space Shuttle Endeavour|Space Shuttle Endeavour]]] Error: {{Lang}}: text has italic markup (help) has a u in it as the spacecraft was named after Captain James Cook's ship, [[[HMS Endeavour|HMS Endeavour]]] Error: {{Lang}}: text has italic markup (help). The special car on Amtrak's Coast Starlight train is known as the Pacific Parlour car, not Pacific Parlor.

The name of the herb savory is thus spelt everywhere, although the related adjective savo(u)ry, like savo(u)r, has a u in the UK. Honor (the name) and arbor (the tool) have -or in Britain, as mentioned above. As a general noun, rigour /ˈrɪɡər/ has a u in the UK; the medical term rigor (often /ˈraɪɡɔːr/) does not, such as in "rigor mortis", which is Latin. Words with the ending -irior, -erior or similar are spelt thus everywhere.

Commonwealth usage

Commonwealth countries normally follow British usage. In Canada -or endings are not uncommon, particularly in the Prairie provinces. In Australia, -or endings enjoyed some use throughout the 19th and 20th centuries, and are still found in some regions, usually in local and regional newspapers, although in recent years most major Australian newspapers have switched from "-or" endings to "-our" endings. The most notable countrywide use of -or is for the Australian Labor Party, which was named in hono(u)r of the American labo(u)r movement. Aside from that, -our is now almost universal. New Zealand English, while sharing some words and syntax with Australian English, follows British usage.

-re, -er

In British English, some words from French, Latin or Greek end with a consonant followed by -re, with the -re unstressed and pronounced /əɹ/. In American English, most of these words have the ending -er. The difference is most common for words ending -bre or -tre: British spellings [calibre, centre, fibre, goitre, litre, lustre, manoeuvre, meagre, metre, mitre, nitre, ochre, reconnoitre, sabre, saltpetre, wikt:sepulchre, sombre, spectre, theatre and titre] Error: {{Lang}}: text has italic markup (help) all have -er in American spelling.

Most English words that today use -er were spelt -re at one time or another. In American English, almost all of these have become -er, while in British English only some of them have. These include chapter, December, disaster, enter, filter, letter, member, minister, monster, November, number, October, oyster, perimeter, parameter, powder, proper, September, sober and tender.

The e preceding the r is kept in American-derived forms of nouns and verbs, for example, [fibers, reconnoitered, centering] Error: {{Lang}}: text has italic markup (help), which are, naturally, [fibres, reconnoitred and centring] Error: {{Lang}}: text has italic markup (help) respectively in British English. Centring is an interesting example, since it is still pronounced as three syllables in British English (/ˈsɛntərɪŋ/), yet there is no vowel letter in the spelling corresponding to the second syllable. It is dropped for other derivations, for example, central, fibrous, spectral. However, such dropping cannot be deemed proof of an -re British spelling: for example, entry and entrance come from enter, which has not been spelt entre for centuries.

The difference relates only to root words; -er rather than -re is universal as a suffix for agentive (reader, winner, user) and comparative (louder, nicer) forms. One outcome is the British distinction of meter for a measuring instrument from metre for the unit of length. However, while "poetic metre" is often -re, pentameter, hexameter etc. are always -er.

Exceptions

Many other words have -er in British English. These include Germanic words like anger, mother, timber and water and Romance words like danger, quarter and river.

The ending -cre, as in acre, lucre, massacre and mediocre, is used in both British and American English to show that the c is pronounced /k/ rather than /s/. The spellings ogre and euchre are also the same in both British and American English.

Theater is the prevailing American spelling used to refer to both the dramatic arts and buildings where stage performances and screenings of films take place (i.e. "movie theaters"); for example, a national newspaper such as The New York Times would use theater in its entertainment section. However, the spelling theatre appears in the names of many New York City theaters on Broadway (cf. Broadway theatre) and elsewhere in the United States. In 2003, the American National Theatre was referred to by The New York Times as the "American National Theater"; but the organization uses "re" in the spelling of its name. The John F. Kennedy Center for the Performing Arts in Washington D.C. has the more common American spelling theater in its references to The Eisenhower Theater, part of the Kennedy Center. Some cinemas outside New York also use the theatre spelling.

Some placenames in the United States use Centre in their names. Examples include the Stonebriar Centre mall, the cities of Rockville Centre and Centreville, Centre County and Centre College. Sometimes, these places were named before spelling changes but more often the spelling merely serves as an affectation.

For British accoutre, the American practice varies: the Merriam-Webster Dictionary prefers the -re spelling, but the The American Heritage Dictionary of the English Language prefers the -er spelling.

More recent French loanwords keep the -re spelling in American English. These are not exceptions when a French-style pronunciation is used (/rə/ rather than /ər/), as with double entendre, genre and oeuvre. However, the unstressed /ər/ pronunciation of an -er ending is used more (or less) often with some words, including cadre, macabre, maître d', Notre Dame, piastre, and timbre.

Commonwealth usage

The -re endings are mostly standard throughout the Commonwealth. The -er spellings are recognized as minor variants in Canada, partly due to American influence, and are sometimes used in proper names (such as Toronto's controversially-named Centerpoint Mall).

-ce, -se

For advice / advise and device / devise, American English and British English both keep the noun/verb distinction (where the pronunciation is -[s] for the noun and -[z] for the verb). For licence / license or practice / practise, British English also keeps the noun/verb distinction (the two words in each pair are homophones with -[s] pronunciation, though). On the other hand, American English uses license and practice for both nouns and verbs (with -[s] pronunciation in both cases too).

American English has kept the Anglo-French spelling for defense and offense, which are usually defence and offence in British English. Likewise, there are the American pretense and British pretence; but derivatives such as defensive, offensive, and pretension are always thus spelt in both systems.

Australian and Canadian usage generally follows British.

-xion, -ction

The spelling connexion is now rare in everyday British usage, its use lessening as knowledge of Latin lessens, and it is not used at all in America: the more common connection has become the standard worldwide. According to the Oxford English Dictionary the older spelling is more etymologically conservative, since the original Latin word had -xio-. The American usage comes from Webster, who ditched -xion in favor of -ction by analogy with verbs like connect.

Complexion (which comes from complex) is standard worldwide and complection is rare. However, the adjective complected (as in "dark-complected"), although sometimes objected to, is standard in the US as an alternative to complexioned, but is not used in this way in the UK, although there is a rare usage to mean complicated.

Greek-derived spellings

-ise, -ize (-isation, -ization)

See also: Oxford spelling

American spelling usually accepts only -ize endings in words like organize, realize and recognize. British spelling uses and -ise ( organise, realise, ' recognise), In Australia and New Zealand -ise spellings strongly prevail: the -ise form is preferred in Australian English at a ratio of about 3:1 according to the Macquarie Dictionary.

Worldwide, -ize endings prevail in scientific writing and are commonly used by many international organizations, such as the International Organization for Standardization and the World Health Organization. The European Union switched from -ize to -ise some years ago in its English language publications, meaning that -ize spellings are found in older legislative acts and -ise spellings in more recent ones. Proofreaders at the EU's Publications Office ensure consistent spelling in official publications such as the Official Journal (where legislation and other official documents are published), but the -ize spelling may be found in other documents.

The same applies to derivatives and inflexions such as colonisation/colonization.

British usage

British English using -ize is known as Oxford spelling and is used in publications of the Oxford University Press, most notably the Oxford English Dictionary (OED). It can be identified using the registered IANA language tag en-GB-oed. The OED lists the -ise form separately, as "a frequent spelling of -IZE", and refuses to list the -ise spellings even as alternatives in the individual entries for words such as realize. It firmly deprecates using -ise for words of Greek origin, saying, "[T]he suffix...whatever the element to which it is added, is in its origin the Greek -ιζειν, Latin -izāre; and, as the pronunciation is also with z, there is no reason why in English the special French spelling in -iser should be followed, in opposition to that which is at once etymological and phonetic". It says "some have used the spelling -ise in English, as in French, for all these words, and some prefer -ise in words formed in French or English from Latin elements, retaining -ize for those of Greek composition". Noah Webster rejected -ise for the same reasons. Henry Watson Fowler's A Dictionary of Modern English Usage quotes the OED and recommends the -ize- spelling. Horace Hart in Hart's Rules for Compositors and Readers at the University Press, Oxford also recommended -ize.

The Cambridge University Press, on the other hand, has long preferred -ise and many reference works, including the Pocket Fowler's Modern English Usage, prefer -ise.

Perhaps as a reaction to the ascendancy of American spelling, the -ize spelling is often (wrongly) seen in the UK as an Americanism, and -ise is more commonly used in UK mass media and newspapers, including The Times, The Daily Telegraph and The Economist. Meanwhile, -ize is used in many British-based academic publications, such as Nature, the Biochemical Journal and The Times Literary Supplement.

Exceptions

Some verbs ending in -ize or -ise do not come from Greek -ιζειν, and their endings are therefore not interchangeable:

• Some words take only the -z- form worldwide, for example capsize, seize (except in the legal phrase to be seised of/to stand seised to), size and prize (only in the "appraise" sense)
• Others take only -s- worldwide: advertise, advise, apprise, arise, circumcise, comprise, compromise, demise, despise, devise, disguise, excise, exercise, franchise, guise, improvise, incise, merchandise (noun), revise, rise, supervise, surmise, surprise, televise, and wise.
• One special case is the verb prise (meaning to force or lever), which is spelt prize in the US and prise everywhere else, including Canada, although in North American English it is almost always replaced by pry, a back-formation from or alteration of prise.

-yse, -yze

The ending -yse is British and -yze is American. Thus, in British English analyse, catalyse, hydrolyse and paralyse, but in American English analyze, catalyze, hydrolyze and paralyze.

Analyse seems to have been the more common spelling in 17th- and 18th-century English, but many of the great dictionaries of that time – John Kersey's of 1702, Nathan Bailey's of 1721 and Samuel Johnson's of 1755 – prefer analyze. In Canada, -yze prevails, just as in the US. In Australia and New Zealand, -yse stands alone.

English verbs ending in -lyse or -lyze are not similar to the Greek verb, which is λύω lúō ("I release"). Instead they come from the noun form λύσις lysis with the -ise or -ize suffix. For example, analyse comes from French analyser, formed by haplology from the French analysiser, which would be spelt analysise or analysize in English.

Hart's Rules for Compositors and Readers at the University Press, Oxford states: "In verbs such as analyse, catalyse, paralyse, -lys- is part of the Greek stem (corresponding to the element -lusis) and not a suffix like -ize. The spelling -yze is therefore etymologically incorrect, and must not be used, unless American printing style is being followed".

-ogue, -og

British and Commonwealth English uses the ending -logue and -gogue while American English usually uses the ending -log and -gog for words like analog(ue), catalog(ue), dialog(ue), demagog(ue), pedagog(ue), monolog(ue), homolog(ue), synagog(ue), etc. Catalogue is sometimes used in the US but catalog is more common. (the inflected forms, cataloged and cataloging v catalogued and cataloguing); analog is standard for the adjective, but both analogue and analog are current for the noun; in all other cases the -gue endings strongly prevail, for example monologue, except for such expressions as dialog box in computing, which are also used in the UK. In Australia, analog is used in its technical and electronic sense, as in analog electronics. In Canada and New Zealand, analogue is used, but analog has some currency as a technical term (e.g. in electronics, as in "analog electronics" as opposed to "digital electronics" and some video-game consoles might have an analog stick).

The -ue is dropped worldwide when forming related words like analogy, analogous, and analogist.

ae and oe

Many words that are written with ae/æ or oe/œ in British English are written with an e in American English. The sound in question is /iː/ or /ɛ/ (or unstressed /ɨ/). Examples (with non-American letter in bold): aesthetics, amoeba, anaemia, anaesthesia, archaeology, caesium, diarrhoea, encyclopaedia, faeces, foetal, gynaecology, haemophilia, leukaemia, oesophagus, oestrogen, orthopaedic, palaeontology, paediatric. Oenology is acceptable in American English but is deemed a minor variant of enology.

Words that can be spelt either way in American English include aesthetics and archaeology (which usually prevail over esthetics and archeology), as well as palaestra, for which the simplified form palestra is described by Merriam-Webster as "chiefly Brit[ish]."

Words that can be spelt either way in British English include encyclopaedia, homoeopathy, mediaeval and foetus. The spellings foetus and foetal are Britishisms based on a mistaken etymology. The etymologically correct original spelling fetus reflects the Latin original and is the standard spelling in medical journals worldwide. The British medical community and The Economist newspaper deem foetus/foetal unacceptable for journal articles and the like.

The Ancient Greek diphthongs <αι> and <οι> were transliterated into Latin as <ae> and <oe>. The ligatures æ and œ were introduced when the sounds became monophthongs, and later applied to words not of Greek origin, in both Latin (for example, cœli) and French (for example, œuvre). In English, which has borrowed words from all three languages, it is now usual to replace Æ/æ with Ae/ae and Œ/œ with Oe/oe. In many cases, the digraph has been reduced to a lone e in all varieties of English: for example, oeconomics, praemium, and aenigma. In others, it is kept in all varieties: for example, phoenix, and usually subpoena. This is especially true of names: Caesar, Oedipus, Phoebe etc. There is no reduction of Latin -ae plurals (e.g. larvae); nor where the digraph <ae>/<oe> does not result from the Greek-style ligature: for example, maelstrom, toe. The British form aeroplane is an instance (compare other aero- words such as aerosol). The now chiefly North American airplane is not a respelling but a recoining, modeled after airship and aircraft. The word airplane dates from 1907, at which time the prefix aero- was trisyllabic, often written aëro-.

In other languages

The American spelling is closer to the usage in a number of other languages using the Latin alphabet. For instance, almost all Romance languages (which tend to have more phonemic spelling) lack the ae and oe spellings (a notable exception being French), as do Swedish, Polish, and others, while Dutch uses them sometimes ("ae" is rare, but "oe" is the normal spelling of the sound [u], while written "u" represents either the sound [y] or [ʏ]). Danish, Icelandic, Norwegian and some others keep the original ligatures. In German, through umlauts, is retained as its equivalent of the ligature, for when written without the umlaut. These words resemble the British usage (i.e. ä becomes ae and ö becomes oe). Likewise, Hungarian uses "é" as a replacement for "ae" (although it becomes "e" sometimes), and the special character "ő" (sometimes "ö") for "oe".

Commonwealth usage

In Canada, e is usually preferred over oe and often over ae as well, just as in the US. In Australia, encyclopedia and medieval are spelt with e rather than ae, as with American usage, and the Macquarie Dictionary also notes an growing tendency towards replacing ae and oe with e worldwide. Elsewhere, the British usage prevails, but the spellings with just e are increasingly used. Manoeuvre is the only spelling in Australia, and the most common one in Canada, where maneuver and manoeuver are also sometimes found.

This shortening is natural, especially since the Canadian Forces in the air and on the oceans are frequently involved in joint maneuvers with the U.S. Air Force and the U.S. Navy. In Canada, oe and ae are sometimes used in the academic and science communities.

Doubled consonants

Doubled in British English

The final consonant of an English word is sometimes doubled in both American and British spelling when adding a suffix beginning with a vowel, for example strip/stripped, which prevents confusion with stripe/striped and shows the difference in pronunciation (see digraph). Generally, this happens only when the word's final syllable is stressed and when it also ends with a lone vowel followed by a lone consonant. In British English, however, a final -l is often doubled even when the final syllable is unstressed. This exception is no longer usual in American English, seemingly because of Noah Webster. The -ll- spellings are nevertheless still deemed acceptable variants by both Merriam-Webster Collegiate and American Heritage dictionaries.

• The British English doubling is used for all inflections (-ed, -ing, -er, -est) and for the noun suffixes -er and -or. Therefore, British English usage is cancelled, counsellor, cruellest, labelled, modelling, quarrelled, signalling, traveller, and travelling. Americans usually use canceled, counselor, cruelest, labeled, modeling, quarreled, signaling, traveler, and traveling.
  • The word parallel keeps a single -l- in British English, as in American English (paralleling, unparalleled), to avoid the unappealing cluster -llell-.
  • Words with two vowels before a final l are also spelt with -ll- in British English before a suffix when the first vowel either acts as a consonant (equalling and initialled; in the United States, equaling or initialed), or belongs to a separate syllable (British fu•el•ling and di•alled; American fu•el•ing and di•aled).
    • British woollen is a further exception due to the double vowel (American: woolen). Also, wooly is accepted in American English, though woolly prevails in both systems.
• Endings -ize /-ise, -ism, -ist, -ish usually do not double the l in British English; for example, normalise, dualism, novelist, and devilish.
  • Exceptions: tranquillise; duellist, medallist, panellist, and sometimes triallist in British English.
• For -ous, British English has a single l in scandalous and perilous, but the "ll" in marvellous and libellous.
• For -ee, British English has libellee.
• For -age, British English has pupillage but vassalage.
• American English sometimes has an unstressed -ll-, as in the UK, in some words where the root has -l. These are cases where the change happens in the source language, which was often Latin. (Examples: bimetallism, cancellation, chancellor, crystallize, excellent, tonsillitis, and raillery.)
• All forms of English have compelled, excelling, propelled, rebelling (notice the stress difference); revealing, fooling (note the double vowel before the l); and hurling (consonant before the l).
• Canadian and Australian English mostly follow British usage.

Among consonants other than l, practice varies for some words, such as where the final syllable has secondary stress or an unreduced vowel. In the United States, the spellings kidnaped and worshiped, which were introduced by the Chicago Tribune in the 1920s, are common. Kidnapped and worshipped are the only standard British spellings.

Miscellaneous:

• British calliper or caliper; American caliper.
• British jewellery; American jewelry. The standard pronunciations (/ˈdʒuːəlri/) do not reflect this difference. According to Fowler, jewelry used to be the "rhetorical and poetic" spelling in the UK. Canada has both, but jewellery is more often used. Likewise, the Commonwealth (including Canada) has jeweller and the US has jeweler for a jewel(le)ry seller.

Doubled in American English

Conversely, there are words where British writers prefer a single l and Americans a double l. In American usage, the spelling of words is usually not changed when they form the main part (not prefix or suffix) of other words, especially in newly formed words and in words whose main part is in common use. Words with this spelling difference include wil(l)ful, skil(l)ful, thral(l)dom, appal(l), fulfil(l), fulfil(l)ment, enrol(l)ment, instal(l)ment. These words have monosyllabic cognates always written with -ll: will, skill, thrall, pall, fill, roll, stall, still. Cases where a single l nevertheless occurs in both American and British English include null→annul, annulment; till→until (although some prefer "til" to reflect the single L in "until", sometimes using an apostrophe ['til]); and others where the connection is not clear or the monosyllabic cognate is not in common use in American English (e.g. null is used mainly as a technical term in law, mathematics, and computer science).

In the UK, ll is sometimes used in distil(l), instil(l), enrol(l), and enthral(l)ment, and often in enthral(l), all of which are always spelt this way in American usage. The former British spellings instal, fulness, and dulness are now quite rare. The Scottish tolbooth is cognate with toll booth, but it has a distinct meaning.

In both American and British usages, words normally spelt -ll usually drop the second l when used as prefixes or suffixes, for example full→useful, handful; all→almighty, altogether; well→welfare, welcome; chill→chilblain.

The British fulfil and American fulfill are never fullfill or fullfil.

Johnson wavered on this issue. His dictionary of 1755 lemmatises distil and instill, downhil and uphill.

Dropped e

British English sometimes keeps silent e when adding suffixes where American English does not. Generally speaking, British English drops it in only some cases in which it is needed to show pronunciation whereas American English only uses it where needed.

• British prefers ageing, American usually aging (compare raging, ageism). For the noun or verb "route", British English often uses routeing, but in America routing is used. The military term rout forms routing everywhere. However, all of these words form "router", whether used in the context of carpentry, data communications, or military. (e.g. "Attacus was the router of the Huns at ....")

Both forms of English keep the silent e in the words dyeing, singeing, and swingeing (in the sense of dye, singe, and swinge), to distinguish from dying, singing, swinging (in the sense of die, sing, and swing). In contrast, the verb bathe and the British verb bath both form bathing. Both forms of English vary for tinge and twinge; both prefer cringing, hinging, lunging, syringing.

• Before -able, British English prefers likeable, liveable, rateable, saleable, sizeable, unshakeable, where American practice prefers to drop the -e; but both British and American English prefer breathable, curable, datable, lovable, movable, notable, provable, quotable, scalable, solvable, usable, and those where the root is polysyllabic, like believable or decidable. Both systems keep the silent e when it is needed to preserve a soft c, ch, or g, such as in traceable, cacheable, changeable; both usually keep the "e" after -dge, as in knowledgeable, unbridgeable, and unabridgeable ("These rights are unabridgeable").
• Both abridgment and the more regular abridgement are current in the US, only the latter in the UK. Likewise for the word lodg(e)ment. Both judgment and judgement are in use interchangeably everywhere, although the former prevails in the US and the latter prevails in the UK except in the practice of law, where judgment is standard. This also holds for abridgment and acknowledgment. Both systems prefer fledgling to fledgeling, but ridgeling to ridgling. Both acknowledgment, acknowledgement, abridgment and abridgement are used in Australia; the shorter forms are endorsed by Australian governments.
• The word "blue" always drops the "e" when forming "bluish" or "bluing".

-ed and -t for past tense

In the UK (as well as Australia and New Zealand) it is common to end some past tense verbs with a "t" as in learnt or dreamt rather than learned or dreamed.

Different spellings for different meanings

• dependant or dependent: British dictionaries distinguish between dependent (adjective) and dependant (noun). In the US, dependent is usual for both noun and adjective, notwithstanding that dependant is also an acceptable variant for the noun form in the US.
• disc or disk: Traditionally, disc used to be British and disk American. Both spellings are etymologically sound (Greek diskos, Latin discus), although disk is earlier. In computing, disc is used for optical discs (e.g. a CD, Compact Disc; DVD, Digital Versatile/Video Disc), by choice of the group that coined and trademarked the name Compact Disc, while disk is used for products using magnetic storage (e.g. hard disks or floppy disks, also known as diskettes). For this limited application, these spellings are used in both the US and the Commonwealth. Solid-state devices also use the spelling "disk".
• enquiry or inquiry: According to Fowler, inquiry should be used in relation to a formal inquest, and enquiry to the act of questioning. Many (though not all) British writers maintain this distinction; the OED, on the other hand, lists inquiry and enquiry as equal alternatives, in that order. Some British dictionaries, such as Chambers 21st Century Dictionary, present the two spellings as interchangeable variants in the general sense, but prefer inquiry for the "formal inquest" sense. In the US, only inquiry is commonly used; the title of the National Enquirer, as a proper name, is an exception. In Australia, inquiry and enquiry are often interchangeable, but inquiry prevails in writing. Both are current in Canada, where enquiry is often associated with scholarly or intellectual research.
• ensure or insure: In the UK (and Australia), the word ensure (to make sure, to make certain) has a distinct meaning from the word insure (often followed by against – to guarantee or protect against, typically by means of an "insurance policy"). The distinction is only about a century old. In American usage, insure may also be used in the former sense, but ensure may not be used in the latter sense. According to Merriam-Webster's usage notes, ensure and insure "are interchangeable in many contexts where they indicate the making certain or [making] inevitable of an outcome, but ensure may imply a virtual guarantee <the government has ensured the safety of the refugees>, while insure sometimes stresses the taking of necessary measures beforehand <careful planning should insure the success of the party>."
• insurance or assurance: In the business of risk transfer, American English speakers will normally refer to life insurance or fire insurance. In British English, "assurance" refers to risk associated with certainty, such as covering death (death is inevitable), whereas "insurance" refers to uncertainty (such as a home insurance policy). In British English "life insurance" is used for a policy covering uncertainty (for example, a pianist's hands may be covered under "life insurance"). Canadian speakers remain more likely than US speakers to use assurance. Assurance is also used for the legal names of several Canadian insurance companies, such as Canada Life Financial or Great-West Life.
• matt or matte: In the UK, matt refers to a non-glossy surface, and matte to the motion-picture technique; in the US, matte covers both.
• programme or program: The British programme is a 19th-century French version of the original program. Program first appeared in Scotland in the 17th century and is the only spelling found in the US. The OED entry, written around 1908 and listing both spellings, said program was preferable, since it conformed to the usual representation of the Greek as in anagram, diagram, telegram etc. In British English, program is the common spelling for computer programs, but for other meanings programme is used. In Australia, program has been endorsed by government writing standards for all meanings since the 1960s, and is listed as the official spelling in the Macquarie Dictionary; see also the name of The The Micallef P(r)ogram(me). In Canada, program prevails, and the Canadian Oxford Dictionary makes no meaning-based distinction between it and programme. However, some Canadian government documents nevertheless use programme for all meanings of the word – and also to match the spelling of the French equivalent.
• tonne or ton: In the UK, Australia, Canada and New Zealand, the spelling tonne refers to the metric unit (1000 kilograms), whereas in the US the same unit is called a metric ton. The unqualified ton usually refers to the long ton (2,240 pounds (1,020 kg)) in the UK and to the short ton (2,000 pounds (910 kg)) in the US (but note that the tonne and long ton differ by only 1.6%, and are roughly interchangeable when accuracy is not critical; ton and tonne are usually pronounced the same in speech).

See also meter/metre, for which there is a British English distinction between these etymologically related forms with different meanings but the standard American spelling is "meter". The spelling used by the International Bureau of Weights and Measures is "metre". This spelling is also the usual one in most English-speaking countries, but only the spelling "meter" is used in American English, and this is officially endorsed by the United States.

Different spellings for different pronunciations

In a few cases, essentially the same word has a different spelling that reflects a different pronunciation. However, in most cases the pronunciation of the words is the same.

As well as the miscellaneous cases listed in the following table, the past tenses of some irregular verbs differ in both spelling and pronunciation, as with smelt (UK) versus smelled (US) (see American and British English differences: Verb morphology).

UK	US	Notes
aeroplane	airplane	Aeroplane, originally a French loanword with a different meaning, is the older spelling. The oldest recorded uses of the spelling airplane are British. According to the OED, "[a]irplane became the standard American term (replacing aeroplane) after this was adopted by the National Advisory Committee for Aeronautics in 1916. Although A. Lloyd James recommended its adoption by the BBC in 1928, it has until recently been no more than an occasional form in British English." In the British National Corpus, aeroplane outnumbers airplane by more than 7:1 in the UK. The case is similar for the British aerodrome and American airdrome, although both of these terms are now obsolete. Aerodrome is used merely as a technical term in Australia, Canada and New Zealand. The prefixes aero- and air- both mean air, with the first coming from the Ancient Greek word ἀήρ (āēr). Thus, the prefix appears in aeronautics, aerostatics, aerodynamics, aeronautical engineering and so on, while the second occurs invariably in aircraft, airport, airliner, airmail etc. In Canada, airplane is more common than aeroplane, although aeroplane is not unknown, especially in parts of French Canada (where it is, however, used only in English – the French term is avion, and the French word aéroplane designates 19th-century flying machines).
aluminium	aluminum	The spelling aluminium is the international standard in the sciences according to the IUPAC recommendations. Humphry Davy, the element's discoverer, first proposed the name alumium, and then later aluminum. The name aluminium was finally adopted to conform with the -ium ending of metallic elements. Canada uses aluminum and Australia and New Zealand aluminium, according to their respective dictionaries.
arse	ass	In vulgar senses "buttocks" ("anus"/"wretch"/"idiot"); unrelated sense "donkey" is ass in both. Arse is very rarely used in the US, though often understood.
behove	behoove	The 19th century had the spelling behove pronounced to rhyme with move. Subsequently, a pronunciation spelling was adopted in America, while in Britain a spelling pronunciation was adopted.
bogeyman	boogeyman or boogerman	It is pronounced /ˈboʊɡimæn/ BOH-gee-man in the UK, so that the American form, boogeyman /ˈbʊɡimæn/, is reminiscent of the 1970s disco dancing "boogie" to the British ear. Boogerman /bʊɡɚmæn/ is common in the Southern US and gives an association with the slang term booger for Nasal mucus while the mainstream American spelling of boogeyman does not.
brent	brant	For the species of goose.
carburettor	carburetor	UK: /ˌkɑːrbəˈrɛtər/; US: /ˈkɑːrbəreɪtər/.
charivari	shivaree, charivari	In America, where both terms are mainly regional, charivari is usually pronounced as shivaree, which is also found in Canada and Cornwall, and is a corruption of the French word.
coupé	coupe	For a two-door car; the horse-drawn carriage is coupé in both (meaning "cut"); unrelated "cup"/"bowl" is always coupe. In the United States, the "e" is accented when it is used as a foreign word.
eyrie	aerie	This noun (not to be confused with the adjective eerie) rhymes with weary and hairy respectively. Both spellings and pronunciations occur in America.
fillet	fillet, filet	Meat or fish. Pronounced the French way (approximately) in the US; Canada follows British pronunciation and distinguishes between fillet, especially as concerns fish, and filet, as concerns certain cuts of beef. McDonald's in the UK use the US spelling "filet" for their Filet-O-Fish.
furore	furor	Furore is a late 18th-century Italian loan-word that replaced the Latinate form in the UK in the following century, and is usually pronounced with a voiced e. The Canadian usage is the same as the American, and Australia has both.
grotty	grody	Clippings of grotesque; both are slang terms from the 1960s.
haulier	hauler	Haulage contractor; haulier is the older spelling.
jemmy	jimmy	In the sense "crowbar".
moustache	mustache	In America, according to the Merriam-Webster Collegiate Dictionary and the The American Heritage Dictionary of the English Language, the British spelling is an also-ran, yet the pronunciation with second-syllable stress is a common variant. In Britain the second syllable is usually stressed.
mum(my)	mom(my)	Mother. Mom is sporadically regionally found in the UK (e.g. in West Midlands English). Some British dialects have mam, and this is often used in Northern English, Hiberno-English, and Welsh English. In the American region of New England, especially in the case of the Boston accent, the British pronunciation of mum is often retained, while it is still spelled mom. In Canada, there are both mom and mum; Canadians often say mum and write mom. In Australia and New Zealand, mum is used. In the sense of a preserved corpse, mummy is always used.
naivety	naïveté	The American spelling is from French, and American speakers generally approximate the French pronunciation as /nɑːiːv(ɨ)ˈteɪ/, whereas the British spelling is nativised, as also the pronunciation /nɑːˈiːv(ɨ)ti/. In the UK, naïveté is a minor variant, used about 20% of the time in the British National Corpus; in America, naivete and naiveté are marginal variants, and naivety is almost unattested.
orientated	oriented	In the UK, Australia and New Zealand, it is common to use orientated (as in family-orientated), whereas in the US oriented is used exclusively (family-oriented). Both words have the same origins, coming from "orient" or its off-shoot "orientation".
pyjamas	pajamas	The 'y' represents the pronunciation of the original Urdu "pāy-jāma", and in the 18th century spellings such as "paijamahs" and "peijammahs" appeared: this is reflected in the pronunciation /paɪˈdʒɑːməz/ (with the first syllable rhyming with "pie") offered as an alternative in the first edition of the Oxford English Dictionary. Both "pyjamas" and "pajamas" are also known from the 18th century, but the latter became more or less confined to the US. Canada follows both British and American usage, with both forms commonplace.
pernickety	persnickety	Persnickety is a late 19th-century American alteration of the Scots word pernickety.
quin	quint	Abbreviations of quintuplet.
scallywag	scalawag	In the United States (where the word originated, as scalawag), scallywag is not unknown.
sledge	sled
speciality	specialty	In British English the standard usage is speciality, but specialty occurs in the field of medicine, and also as a legal term for a contract under seal. In Canada, specialty prevails. In Australia both are current.
titbit	tidbit	According to the Oxford English Dictionary, the oldest form was "tyd bit", and the alteration to "titbit" was probably under the influence of the obsolete word "tit", meaning a small horse or girl.
whilst	while	Penguin Working Words recommends while only, and notes that whilst is old-fashioned. The Cambridge Guide to English Usage and Merriam–Webster's Dictionary of English Usage comment on its regional character, and note that it is rare in American usage. It is thus safer to use only while in international English. (See the article While for further sources deprecating the use of whilst, and cautioning about uses of while.)

Miscellaneous spelling differences

In the table below, the more common spellings are on top. Note that this list includes words that were historically spelt differently in American/British English but today are usually spelt the same.

UK	US	Remarks
ache	ache, ake	Ake is the older spelling of the verb. It was changed to ache in the 18th century as it was wrongly thought to come from the Greek akhos.
acre	acre, aker	The word was spelt aker in Middle English and æcer in Old English.
adze	adz, adze
annexe	annex	To annex is the verb in both British and American usage; however, when speaking of an annex(e) – the noun referring to an extension of a main building – the root word is usually spelt with an -e at the end in the UK, but in the US it is not.
artefact, artifact	artifact	In British English, artefact is the main spelling and artifact a minor variant. In American English, artifact is the usual spelling. Canadians prefer artifact and Australians artefact, according to their respective dictionaries. Artefact reflects Arte-fact(um), the Latin source.
artisan	artisan, artizan
axe	ax, axe	Both the noun and verb. The word comes from Old English æx. In the US, both spellings are acceptable and commonly used. The Oxford English Dictionary states that "the spelling ax is better on every ground, of etymology, phonology, and analogy, than axe, which became prevalent in the 19th century; but it ["ax"] is now disused in Britain". In the US, "ax" is used for the tool whereas "axe" is used for the weapon.
brasier	brasier, brazier
camomile, chamomile	chamomile, camomile	The word derives, via French and Latin, from Greek χαμαίμηλον ("earth apple"). The more common British spelling "camomile", corresponding to the immediate French source, is the older in English, while the spelling "chamomile" more accurately corresponds to the ultimate Latin and Greek source. In the UK, according to the OED, "the spelling cha- is chiefly in pharmacy, after Latin; that with ca- is literary and popular". In the US chamomile dominates in all senses.
cheque	check	In banking. Hence pay cheque and paycheck. Accordingly, the North American term for what is known as a current account or cheque account in the UK is spelt chequing account in Canada and checking account in the US. Some American financial institutions, notably American Express, use cheque, but this is merely a trademarking affectation.
chequer	checker	As in chequerboard/checkerboard, chequered/checkered flag etc. In Canada as in the US.
chilli	chili, chile	The original Mexican Spanish word is spelled chile. In Merriam-Webster's Collegiate Dictionary, chile and chilli are given as also variants.
cipher, cypher	cipher
cosy	cozy	In all senses (adjective, noun, verb).
dyke	dike
domicile	domicile, domicil
doughnut	doughnut, donut	In the US, both are used, with donut indicated as a variant of doughnut. In the UK, donut is indicated as an American variant for doughnut.
draught	draft	British English usually uses draft for all senses as the verb; for a preliminary version of a document; for an order of payment (bank draft), and for military conscription (although this last meaning is not as common as in American English). It uses draught for drink from a cask (draught beer); for animals used for pulling heavy loads (draught horse); for a current of air; for a ship's minimum depth of water to float; and for the game draughts, known as checkers in America. It uses either draught or draft for a plan or sketch (but almost always draughtsman in this sense; a draftsman drafts legal documents). American English uses draft in all these cases, including draftsman (male or female) (although in regard to drinks, draught is sometimes found). Canada uses both systems; in Australia, draft is used for technical drawings, is accepted for the "current of air" meaning, and is preferred by professionals in the nautical sense. The pronunciation is always the same for all meanings within a dialect (RP /ˈdrɑːft/, General American /ˈdræft/). The spelling draught is older; draft appeared first in the late 16th century.
gauge	gage, gauge	Both spellings have existed since Middle English.
gauntlet	gauntlet, gantlet	When meaning "ordeal", in the phrase running the ga(u)ntlet, some American style guides prefer gantlet. This spelling is unused in Britain and less usual in America than gauntlet. The word is an alteration of earlier gantlope by folk etymology with gauntlet ("armored glove"), always spelt thus.
gazelle	gazelle, gazel	The word comes from French gazelle, which was spelt gazel in Old French.
glycerine	glycerin, glycerine	Scientists use the term glycerol, but both spellings are used sporadically in the US.
grey	gray	Grey became the established British spelling in the 20th century, pace Dr Johnson and others, and it is but a minor variant in American English, according to dictionaries. Canadians tend to prefer grey. The non-cognate greyhound was never grayhound. Both Grey and Gray are found in proper names everywhere in the English-speaking world. The two spellings are of equal antiquity, and the Oxford English Dictionary states that "each of the current spellings has some analogical support".
grille	grill, grille	In the US, "grille" refers to that of an automobile, whereas "grill" refers to a device used for heating food.
hearken	harken	The word comes from hark. The spelling hearken was likely influenced by hear.
jail, gaol	jail	In the UK, gaol and gaoler are used sometimes, apart from literary usage, chiefly to describe a medieval building and guard. Both spellings go back to Middle English: gaol was a loanword from Norman French, while jail was a loanword from central (Parisian) French. In Middle English the two spellings were associated with different pronunciations. In current English the word, however spelt, is always given the pronunciation originally associated only with the jail spelling (/ˈdʒeɪl/). The survival of the gaol spelling in British English is "due to statutory and official tradition".
kerb	curb	For the noun designating the edge of a roadway (or the edge of a British pavement/ American sidewalk/ Australian footpath). Curb is the older spelling, and in the UK and US it is still the proper spelling for the verb meaning restrain.
(kilo)gram, (kilo)gramme	(kilo)gram	(Kilo)gramme is used sometimes in the UK but never in the US. (Kilo)gram is the only spelling used by the International Bureau of Weights and Measures.
liquorice	licorice	The American spelling is nearer the Old French source licorece, which is ultimately from Greek glykyrrhiza. The British spelling was influenced by the unrelated word liquor. Licorice prevails in Canada and it is common in Australia, but it is rarely found in the UK. Liquorice is all but nonexistent in the US ("Chiefly British", according to dictionaries).
mollusc	mollusk, mollusc	The related adjective may be spelt molluscan or molluskan.
mould	mold	In all senses of the word. The American spelling is the older of the two. In Canada, both words have wide currency. When speaking of the noun describing a form for casting a shape, the US will also use the "mould" spelling, but defaults to "mold" when referring to the fruiting bodies of tiny fungi.
moult	molt
neurone, neuron	neuron
omelette	omelet, omelette	The omelet spelling is the older of the two, in spite of the etymology (French omelette). Omelette prevails in Canada and in Australia.
opaque	opaque, opake	The opake spelling is the older of the two. The word was re-spelt in the 17th century to match the French spelling. Nevertheless, the older spelling lingered and appeared in Webster's dictionaries.
partisan	partisan, partizan
phantasm	phantasm, fantasm	The word was originally spelt in English with an f but was re-spelt in the 16th century. It is related to the words fantasy and fantastic, which were for a time spelt phantasie and phantastique.
phantom	phantom, fantom	The fantom spelling is the older of the two and has existed since Middle English. It is related to the words phantasm/fantasm, fantasy and fantastic.
phoney	phony	The American spelling is the older of the two. The word originated in America and made its widespread appearance in Britain during the Phoney War. Phony is famously used often in The Catcher in the Rye.
plough	plow	Both spellings have existed since Middle English. The OED records several dozen variants. In the UK, plough has been the standard spelling for about 300 years. Although plow was Noah Webster's pick, plough continued to have some currency in the US, as the entry in Webster's Third (1961) implies. Newer dictionaries label plough as "chiefly British". The word snowplough/snowplow, originally an Americanism, predates Webster's dictionaries and was first recorded as snow plough. Canada has both plough and plow, although snowplough is much rarer there than snowplow. In the US, "plough" sometimes describes a horsedrawn kind while "plow" refers to a gasoline (petrol) powered kind. The American spelling appears to relate to the Latin "plovum".
primaeval	primeval	Primeval is also common in UK but etymologically 'ae' is nearer the Latin source primus first + aevum age.
rack and ruin	wrack and ruin	Several words like "rack" and "wrack" have been conflated, with both spellings thus accepted as variants for senses connected to torture (orig. rack) and ruin (orig. wrack, cf. wreck) In "(w)rack and ruin", the W-less variant is now prevalent in the UK but not the US. The term, however, is rare in the US.
rhyme	rhyme, rime	In the context of sound and music, the word was spelt rime or ryme in Middle English. The term 'rime ice' is unrelated and is spelt the same everywhere.
sceptic (-al, -ism)	skeptic (-al, -ism)	The American spelling, akin to Greek, is the earliest known spelling in English. It was preferred by Fowler, and is used by many Canadians, where it is the earlier form. Sceptic also pre-dates the European settlement of the US, and it follows the French sceptique and Latin scepticus. In the mid-18th century, Dr Johnson's dictionary listed skeptic without comment or alternative, but this form has never been popular in the UK; sceptic, an equal variant in the old Webster's Third (1961), has now become "chiefly British". Australians generally follow the British usage (with the notable exception of the Australian Skeptics). All of these versions are pronounced with a hard "c", though in French that letter is silent and the word is pronounced like septique.
smoulder	smolder	The American spelling is the older of the two and has existed since Middle English.
stead(fast)	stead(fast), sted(fast)
storey	story	Level of a building. The plurals are storeys and stories respectively. The letter "e" is used in the UK and Canada to differentiate between levels of buildings and a story as in a literary work. Story is the earlier spelling. The Oxford English Dictionary states that this word is "probably the same word as story [in its meaning of "narrative"] though the development of sense is obscure.
sulphate	sulfate, sulphate
sulphur	sulfur, sulphur	Sulfur is the preferred spelling by the International Union of Pure and Applied Chemistry (IUPAC) and by the UK's Royal Society of Chemistry (RSC). During the Middle English period the word was spelt with an f. However, sulphur was preferred by Dr Johnson. It is still used by British and Irish scientists, and it is still actively taught in British and Irish schools. It prevails in Canada and Australia, and it is also found in some American place names (e.g. Sulphur, Louisiana and White Sulphur Springs, West Virginia). American English usage guides suggest sulfur for technical usage, and both sulfur and sulphur in common usage and in literature. The variation between f and ph spellings is also found in the word's ultimate source: Latin sulfur, sulphur.
through	through, thru	"Thru" is typically used in the US as shorthand.
throughout	throughout, thruout
towards, toward	toward, towards
tyre	tire	The outer portion of a wheel. In Canada as in the US. Tire is the older spelling, but both were used in the 15th and 16th centuries (for a metal tire). Tire became the settled spelling in the 17th century but tyre was revived in the UK in the 19th century for rubber / pneumatic tyres, possibly because it was used in some patent documents, though many continued to use tire for the iron variety. The Times newspaper was still using tire as late as 1905. For the verb meaning "to grow weary" both American and British English use only the tire spelling.
vice	vise, vice	The two-jawed workbench tool. Americans and Canadians retain the very old distinction between vise (the tool) and vice (the sin, and also the Latin prefix meaning a "deputy"), both of which are vice in the UK and Australia. Thus, Americans have Vice-Admiral, Vice-President, and Vice-Principal, but never Vise- for any one of these.
vineyard	vineyard, vinyard
visor	visor, vizor
woe(ful)	woe(ful), wo(ful)
yoghurt, yogurt	yogurt, yoghurt	Yoghurt is an also-ran in the US, as is yoghourt in the UK. Although the Oxford Dictionaries have always preferred yogurt, in current British usage yoghurt seems to be prevalent. In Canada, yogurt prevails, despite the Canadian Oxford preferring yogourt, which has the advantage of being bilingual (English and French). In Australia as in the UK. Whatever the spelling is, the word has different pronunciations: in the UK /ˈjɒɡɚt/ or /ˈjoʊɡɚt/, only /ˈjoʊɡɚrt/ in America, Ireland, and Australia. The word comes from the Turkish language word yoğurt. The voiced velar fricative represented by ğ in the modern Turkish (Latinic) alphabet was traditionally written gh in romanizations of the Ottoman Turkish (Arabic) alphabet used before 1928.

Compounds and hyphens

British English often prefers hyphenated compounds, such as counter-attack, whereas American English discourages the use of hyphens in compounds where there is no compelling reason, so counterattack is much more common. Many dictionaries do not point out such differences. Canadian and Australian usage is mixed, although Commonwealth writers generally hyphenate compounds of the form noun plus phrase (such as editor-in-chief). Commander-in-chief prevails in all forms of English.

• any more or anymore: In sense "any longer", the single-word form is usual in North America and Australia but unusual elsewhere, at least in formal writing. Other senses always have the two-word form; thus Americans distinguish "I couldn't love you anymore [so I left you]" from "I couldn't love you any more [than I already do]". In Hong Kong English, any more is always two words.
• for ever or forever: Traditional British English usage makes a distinction between for ever, meaning for eternity (or a very long time into the future), as in "If you are waiting for income tax to be abolished you will probably have to wait for ever"; and forever, meaning continually, always, as in "They are forever arguing". In British usage today, however, forever prevails in the "for eternity" sense as well, in spite of several style guides maintaining the distinction. American writers usually use forever regardless of which sense they intend (although forever in the sense of "continually" is comparatively rare in American English, having been displaced by always).
• near by or nearby: Some British writers make the distinction between the adverbial near by, which is written as two words, as in, "No one was near by"; and the adjectival nearby, which is written as one, as in, "The nearby house". In American English, the one-word spelling is standard for both forms.

Acronyms and abbreviations

Proper names formed as proper acronyms are often written in title case by Commonwealth writers, but usually as upper case by Americans: for example, Nasa / NASA or Unicef / UNICEF. This does not apply to most pure initialisms, such as US, IBM, or PRC (the People's Republic of China). However, it is sometimes done in the UK, such as Pc (Police Constable).

Contractions, where the final letter is present, are often written in British English without full stops/periods (Mr, Mrs, Dr, St, Ave). Abbreviations where the final letter is not present generally do take full stops/periods (such as vol., etc., i.e., ed.); British English shares this convention with the French: Mlle, Mme, Dr, Ste, but M. for Monsieur. In American and Canadian English, abbreviations like St., Ave., Mr., Mrs., Ms., Dr., and Jr., always require periods. Some initials are usually upper case in the US but lower case in the UK: liter/litre and its compounds ("2 L or 25 mL" vs "2 l or 25 ml"); and ante meridiem and post meridiem (10 P.M. or 10 PM vs 10 p.m. or 10 pm). Both AM/PM and a.m./p.m. are acceptable in American English, though AM/PM is more common.

Punctuation

The use of quotation marks, also called inverted commas, is complicated by the fact that there are two kinds: single quotation marks (') and double quotation marks ("). As a general rule, British usage has in the past usually preferred single quotation marks for ordinary use, but double quotation marks are now increasingly common; American usage has always preferred double quotation marks.

The convention used to be, and in American English still is, to put full stops (periods) and commas inside the quotation marks, irrespective of the sense. British English has moved away from this style while American English has kept it. British style now prefers to punctuate according to the sense, in which punctuation marks only appear inside quotation marks if they were there in the original. Moreover, formal British English practice requires a full stop to be put inside the quotation marks if the quoted item is a full sentence that ends where the main sentence ends, but it is common to see the stop outside the ending quotation marks.
