glee (n.) Look up glee at Dictionary.com
Old English gliu, gliw "entertainment, mirth, jest, play, sport," presumably from a Proto-Germanic *gleujam but absent in other Germanic languages except for the rare Old Norse gly "joy;" probably related to glad. A poetry word in Old English and Middle English, obsolete c.1500-c.1700, it somehow found its way back to currency late 18c. In Old English, an entertainer was a gleuman (female gleo-mægden). Glee club (1814) is from the secondary sense of "unaccompanied part-song" (1650s) as a form of musical entertainment.
