Definition for y (8 of 10)

-y

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 of -y

late Middle English (Scots), orig. in names; of uncertain origin; baby and puppy, now felt as having this suffix, may be of different derivation
