|Close front unrounded vowel|
Legend: unrounded • rounded
The close front unrounded vowel, or high front unrounded vowel, is a type of vowel sound that occurs in most spoken languages, represented in the International Phonetic Alphabet by the symbol i. It is similar to the vowel sound in the English word meet—and often called long-e in American English. Although in English this sound has additional length (usually being represented as /iː/) and is not normally pronounced as a pure vowel (it is a slight diphthong), some dialects have been reported to pronounce the phoneme as a pure sound. A pure [i] sound is also heard in many other languages, such as French, in words like chic.
The close front unrounded vowel is the vocalic equivalent of the palatal approximant [j]. They alternate with each other in certain languages, such as French, and in the diphthongs of some languages, [i̯] with the non-syllabic diacritic and [j] are used in different transcription systems to represent the same sound.
Languages that use the Latin script commonly use the letter ⟨i⟩ to represent this sound, though there are some exceptions: in English orthography that letter is usually associated with /aɪ/ (as in bite) or /ɪ/ (as in bit), and /iː/ is more commonly represented by ⟨e⟩, ⟨ea⟩, ⟨ee⟩, ⟨ie⟩ or ⟨ei⟩, as in the words scene, bean, meet, niece, conceive; (see Great Vowel Shift). Irish orthography reflects both etymology and whether preceding consonants are broad or slender, so such combinations as ⟨aí⟩, ⟨ei⟩, and ⟨aío⟩ all represent /iː/.
