I The ninth letter in the alphabets of Western Europe. Its form in the Phoeni- cian and early Greek alphabets, from which it is derived, somewhat resembled a narrow upright Z. (See Alphabet.) After various modilications this was straightened into its present shape. The Grwk designation, iolu, of the letter is an adaptation of its Phu'nician name yod, 'a hand.' The dot over our small i did not come into use until the fourteenth century. Phonetic Character. The 'short i' in Eng- lish is described as a high-front or palatal vowel, made by the blade of the tongue appro.ximating the forward part of the palate or roof of the mouth— the sound heard in it. When approxi- mated so far as to make a partial contact or closure, this passes over into a .semi-vocalie or consonantal y, as in you (i«), although in Eng- lish the y is often not written, e.g. minion, million; other variations may be noticed in charily, bird. The corresponding _ 'long i,' common in EOropean languages, is found in machine, police, pique. This is sometimes known as the "long e' .sotind in receive, helicve, scat. The sound cnnimonly called 'long i' in English, uide, ice, and the name of the letter itself (i pronounced eye), is really a diphthong, like aisle, made by premature opening of the lengthened vowel under stress-accent. This phonetic change from the older character of the sound was going on during the Middle Period of transition into the Modern English, so that it is now a phonetic rule that Anglo-Saxon or Old English I regularly calls for a diphthongal long i in modem English, e.g. OE. icfrf, iHf/ = Mod. Eng. icirfc. riii7c. Historically the linguistic char- acter of 1 is fairly stable, Indo-Germ.

The term is also applied by analogy to English verse wherein stressed and unstressed syllables corre- spond to a long syllable followed by a short sylla- ble in Latin or Greek verse.
