 Y Y, the twenty-fifth letter of the English alphabet, at the beginning of a word or syllable, except when a prefix (see Y-), is usually a fricative vocal consonant; as a prefix, and usually in the middle or at the end of a syllable, it is a vowel.  See Guide to Pronunciation, §§ 145, 178-9, 272.
 Note: It derives its form from the Latin Y, which is from the Greek Υ, originally the same letter as V. Etymologically, it is most nearly related to u, i, o, and j. g; as in full, fill, AS. fyllan; E. crypt, grotto; young, juvenile; day, AS. dæg.  See U, I, and J, G.
 Note:Y has been called the Pythagorean letter, because the Greek letter Υ was taken to represent the sacred triad, formed by the duad proceeding from the monad; and also because it represents the dividing of the paths of vice and virtue in the development of human life.
