Copacetic (Adjective)

Pronunciation: [ko-pê-'se-tik]

Definition 1: More than satisfactory, fine, running very smoothly, going quite well.

Usage 1: This term is rarely used outside North America. It was popularized by Bill "Bojangles" Robinson and later spread among developers of the U.S. space program. Its profile has lowered since then. Also spelled "copasetic."

Suggested usage: The term is perfect if you want to express an intensified "O.K." without saying "excellent" or "outstanding." "That solution isn't just good, it's positively copacetic." "Things are not so copacetic at the office right now; the new director is a bit overbearing."

Etymology: Entered the language circa 1919 among black jazz musicians, but its etymology is unknown. Speculations are that it comes from southern U.S. Black English, from the Yiddish phrase kol b'tzedek "all with justice," the Creole French word coupersètique "able to cope with things," or from the Chinook word copasenee, "everything is satisfactory."
