  Y \Y\ (w[imac]).
     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, [sect][sect] 145, 178-9,


     272.
     [1913 Webster]
  
     Note: It derives its form from the Latin Y, which is from the
           Greek [Upsilon], 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. d[ae]g. See {U}, {I},
           and {J}, {G}.
           [1913 Webster]
  
     Note: Y has been called the Pythagorean letter, because the
           Greek letter [Upsilon] 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.
           [1913 Webster]

     [1913 Webster] Y

From The Collaborative International Dictionary of English v.0.48 [gcide]:

  Y- \Y-\, or I- \I-\ . [OE. y-, i-, AS. ge-, akin to D. & G. ge-,
     OHG. gi-, ga-, Goth. ga-, and perhaps to Latin con-;
     originally meaning, together. Cf. {Com-}, {Aware}, {Enough},
     {Handiwork}, {Ywis}.]
     A prefix of obscure meaning, originally used with verbs,
     adverbs, adjectives, nouns, and pronouns. In the Middle
     English period, it was little employed except with verbs,
     being chiefly used with past participles, though occasionally
     with the infinitive. Ycleped, or yclept, is perhaps the only
     word not entirely obsolete which shows this use.
     [1913 Webster]
  
           That no wight mighte it see neither yheere. --Chaucer.
     [1913 Webster]
  
           Neither to ben yburied nor ybrent.       --Chaucer.
     [1913 Webster]
  
     Note: Some examples of Chaucer's use of this prefix are; ibe,
           ibeen, icaught, ycome, ydo, idoon, ygo, iproved,
           ywrought. It inough, enough, it is combined with an
           adjective. Other examples are in the Vocabulary.
           [1913 Webster] Spenser and later writers frequently
           employed this prefix when affecting an archaic style,
           and sometimes used it incorrectly.
