I (named i /ˈ/, plural ies)[1] is the ninth letter and the third vowel in the ISO basic Latin alphabet.

In Semitic, the letter may have originated in a hieroglyph for an arm that represented a voiced pharyngeal fricative (/ʕ/) in Egyptian, but was reassigned to /j/ (as in English "yes") by Semites, because their word for "arm" began with that sound. This letter could also be used to represent /i/, the close front unrounded vowel, mainly in foreign words.

The Greeks adopted a form of this Phoenician yodh as their letter iota (Ι, ι) to represent /i/, the same as in the Old Italic alphabet. In Latin (as in Modern Greek), it was also used to represent /j/ and this use persists in the languages that descended from Latin. The modern letter 'j' originated as a variation of 'i', and both were used interchangeably for both the vowel and the consonant, coming to be differentiated only in the 16th century.[2] The dot over the lowercase 'i' is sometimes called a tittle. In the Turkish alphabet, dotted and dotless I are considered separate letters, representing a front and back vowel, respectively, and both have uppercase ('I', 'İ') and lowercase ('ı', 'i') forms.

In modern English, 'i' represents several different sounds, either a "long" diphthong /aɪ/ as in kite, which developed from Middle English /iː/ after the Great Vowel Shift of the 15th century, or the "short" /ɪ/ as in bill.

Use in English[edit]

In English orthography, the letter 'i' has a "long" and "short" sound like the other vowel letters as a result of the Great Vowel Shift: "long" 'i' has the sound // and "short" 'i' has the sound /ɪ/. The letter 'i' may also take the sound // in loanwords from other languages. Some digraphs that include 'i' are ai, oi, ei, ui and ie.

The letter 'i' is the fifth most common letter in the English language.[3]

The English first-person singular nominative pronoun is "I", pronounced // and always written with a capital letter. This pattern arose for basically the same reason that lowercase "i" acquired a dot: so it wouldn't get lost in manuscripts before the age of printing:

The capitalized “I” first showed up about 1250 in the northern and midland dialects of England, according to the Chambers Dictionary of Etymology. Chambers notes, however, that the capitalized form didn’t become established in the south of England “until the 1700s (although it appears sporadically before that time).”
Capitalizing the pronoun, Chambers explains, made it more distinct, thus “avoiding misreading handwritten manuscripts.”[4]

Use in other languages[edit]

In many languages' orthographies, 'i' is used to represent the sound /i/ or, more rarely, /ɪ/.

Other Usage[edit]

Lowercase "i" is used in mathematics to denote the square root of −1.

Forms and variants[edit]

In some sans serif typefaces, the uppercase letter I, 'I' may be difficult to distinguish from the lowercase letter L, 'l', the vertical bar character '|', or the digit one '1'. In serifed typefaces, the capital form of the letter has both a baseline and a cap-height serif, while the lowercase L has generally a hooked ascender and a baseline serif.

The uppercase I does not have a dot (tittle) while the lowercase i has one in most Latin-derived alphabets. However, some schemes, such as the Turkish alphabet, have two kinds of I: dotted (İi) and dotless (Iı).

The uppercase I has two kinds of shapes, with serifs (I with crossbars.svg) and without serifs (I without crossbars.svg). Usually these are considered equivalent, but they are distinguished in some extended Latin alphabet systems such as the 1978 version of the African reference alphabet. In that system, the former is the uppercase counterpart of ɪ and the latter is the counterpart of 'i'.
