2 
a noun-forming suffix with a variety of functions in contemporary English, added to monosyllabic bases to create words that are almost always informal. Its earliest use, probably still productive, was to form endearing or familiar names or common nouns from personal names, other nouns, and adjectives (Billy; Susie; birdie; doggie; granny; sweetie; tummy). The hypocoristic feature is absent in recent coinages, however, which are simply informal and sometimes pejorative (boonies; cabby; groupie; hippy; looie; Okie; preemie; preppy; rookie). Another function of -y2 (-ie) is to form from adjectives nouns that denote exemplary or extreme instances of the quality named by the adjective (baddie; biggie; cheapie; toughie), sometimes focusing on a restricted, usually unfavorable sense of the adjective (sharpie; sickie; whitey). A few words in which the informal character of -y2 (-ie) has been lost are now standard in formal written English (goalie; movie).
Also, -ie.
Compare -o, -sy.

Origin:
late ME (Scots), orig. in names; of uncert. orig.; baby and puppy, now felt as having this suffix, may be of different derivation

Word Origin & History

Y 
a late-developing letter in Eng. Called ipsilon in Ger., upsilon in Gk., the Eng. name is of obscure origin. The sound at the beginning of yard, yes, yield, etc. is from O.E. words with initial g- as in got and y- as in yet, which were considered the same sound and often transcribed as a character that looks something like 3 (but with a flat top and lower on the line of text), known as yogh. The system was altered by Fr. scribes, who brought over the continental use of -g- and from the early 1200s used -y- and sometimes -gh- to replace 3. There's a good, in-depth discussion of yogh here. As short for YMCA, YWCA, YMHA first recorded 1915.

y- 
perfective prefix, in y-clept, etc.; a deliberate archaism, introduced by Spenser and his imitators, representing an authentic M.E. prefix, from O.E. ge-, originally meaning "with, together" but later a completive or perfective element, from P.Gmc. *ga-. It is still living in Ger. and Du. ge-, and survives, disguised, in some Eng. words (e.g. alike, aware).

-y  (3)
suffix in pet proper names (e.g. Johnny, Kitty), first recorded in Scottish, c.1400; became frequent in Eng. 15c.-16c. Extension to surnames seems to date from c.1940. Use with common nouns seems to have begun in Scot. with laddie (1546) and become popular in Eng. due to Burns' poems, but the same formation appears to be represented much earlier in baby and puppy.
