\I\ ([imac]). 1. I, the ninth letter of the English alphabet, takes its form from the Ph[oe]nician, through the Latin and the Greek. The Ph[oe]nician letter was probably of Egyptian origin. Its original value was nearly the same as that of the Italian I, or long e as in mete. Etymologically I is most closely related to e, y, j, g; as in dint, dent, beverage, L. bibere; E. kin, AS. cynn; E. thin, AS. [thorn]ynne; E. dominion, donjon, dungeon. In English I has two principal vowel sounds: the long sound, as in p[=i]ne, [=i]ce; and the short sound, as in p[i^]n. It has also three other sounds:
(a) That of e in term, as in thirst.
(b) That of e in mete (in words of foreign origin), as in machine, pique, regime.
(c) That of consonant y (in many words in which it precedes another vowel), as in bunion, million, filial, Christian, etc. It enters into several digraphs, as in fail, field, seize, feign. friend; and with o often forms a proper diphtong, as in oil, join, coin. See Guide to Pronunciation, [sect][sect] 98-106. Note: The dot which we place over the small or lower case i dates only from the 14th century. The sounds of I and J were originally represented by the same character, and even after the introduction of the form J into English dictionaries, words containing these letters were, till a comparatively recent time, classed together. 2. In our old authors, I was often used for ay (or aye), yes, which is pronounced nearly like it. 3. As a numeral, I stands for 1, II for 2, etc.
