Prefix

This article is about the linguistic feature. For other uses, see Prefix (disambiguation).

A prefix is an affix which is placed before the stem of a word.[1] Adding it to the beginning of one word changes it into another word. For example, when the prefix un- is added to the word happy, it creates the word unhappy. Particularly in the study of languages, a prefix is also called a preformative, because it alters the form of the words to which it is affixed.

Prefixes, like other affixes, can be either inflecional, creating a new form of the word with the same basic meaning and same lexical category (but playing a different role in the sentence), or derivational, creating a new word with a new semantic meaning and sometimes also a different lexical category.[2] Prefixes, like all other affixes, are usually bound morphemes.[1]

In English, there are no inflectional prefixes; English uses suffixes instead for that purpose.

The word prefix is itself made up of the stem fix (meaning "attach", in this case), and the prefix pre- (meaning "before"), both of which are derived from Latin roots.

In English[edit]

List of English derivational prefixes[edit]

Main article: English prefixes

In English, a fairly comprehensive list, although not exhaustive, is the following. Depending on precisely how one defines a derivational prefix, some of the neoclassical combining forms may or may not qualify for inclusion in such a list. This list takes the broad view that acro- and auto- count as English derivational prefixes because they function the same way that prefixes such as over- and self- do.

As for numeral prefixes, only the most common members of that class are included here. There is a large separate table covering them all at Numeral prefix > Table of number prefixes in English.

Hyphenation[edit]

The choice between hyphenation or solid styling for prefixes in English is covered at Hyphen > Prefixes and suffixes.

In other languages[edit]

Japanese[edit]

The most commonly used prefix in Japanese, o-, is used as part of the honorific system of speech. It is a marker for politeness, showing respect for the person or thing it is affixed to.[3]

Bantu languages[edit]

In the Bantu languages of Africa, which are agglutinating, the noun class is conveyed through prefixes, which is declined and agrees with all of its arguments accordingly.[4]

Example from Luganda[edit]

Noun class Prefix
1 o-mu-
1a
2 a-ba-
3 o-mu-
4 e-mi-
5 e-ri-/CC-
6 a-ma-
7 e-ki-
8 e-bi-
9 e-N-
10 e-N-/zi-
  • The one, old, fat farmer goes.
ò-mú-límí ò-mú-néné ò-mú-kâddé ò-mú à-∅-gênda
ag-1-farmer ag-1-fat ag-1-old ag. one he-Pres-go

Navajo[edit]

Verbs in the Navajo language are formed from a word stem and multiple affixes. For example, each verb requires one of four non-syllabic prefixes (, ł, d, l) to create a verb theme.[5]

Sunwar[edit]

In the Sunwar language of Eastern Nepal, the prefix ma- म is used to create negative verbs. It is the only verbal prefix in the language.

  • Bad child! (scolding)
ma.rimʃo al
NEG.nice child[6]

Russian[edit]

As a part of the formation of nouns, prefixes are less common in Russian than suffixes, but alter the meaning of a word.

в- and ложение 'position' becomes вложение 'investment'
пре and образование 'formation (verb)' becomes преобразование 'transformation'[7]

German[edit]

In German, derivatives formed with prefixes may be classified in two categories: those used with substantives and adjectives, and those used with verbs.[8] For derivative substantives and adjectives, only two prefixes are still in use as of 1970: un-, which expresses negation (as in Ungesund from Gesund), and ur-, which means "original, primitive" in substantives, and has an emphatic function in adjectives. ge- expresses union or togetherness.[8]

On the other hand, verbal prefixes are still much in use: be-, er-, ent-, ge-, ver-, zer-, and miß-.[8] be- expresses strengthening or generalization. ent- expresses negation. ge- indicates the completion of an action, and that's why its most common use has become the forming of the past participle of verbs; ver- has an emphatic function, or it is used to turn a substantive or an adjective into a verb.[8] In some cases, the prefix particle ent- (negation) can be considered the opposite of particle be-, while er- can be considered the opposite of ver-.[9][10]

The prefix er- usually indicates the successful completion of an action, and sometimes the conclusion means death.[11] With fewer verbs, it indicates the beginning of and action.[8][11] The prefix er- is also used to form verbs from adjectives (e.g. erkalten is equivalent to kalt werden which means to get cold).[11]
