what is it called to use the term "pretty good"? —This unsigned comment was added by 220.127.116.11 (talk • contribs) 01:38, 30 October 2007.
Pretty good is a compound adjective made from adverb + adjective. It's compound because it's a multiword form. Pretty here means by a high degree, similar to really, not like it's adjectival use in pretty woman.
