Copacetic Pundit

There's a word I haven't heard in a while, "copacetic." I'm going to look it up in the unabridged as my standard dictionary states that the origin is unknown. Wow! This is the first word I have not been able to find in my Webster's Deluxe Unabridged Dictionary with 320,000 definitions. It does not list copacetic! Neither does my Microsoft PC thesaurus.

Very mysterious. Not satisfactory at all. Definitely NOT copacetic.

All it says in my standard dictionary is copacetic, adj. very satifactory. Origin unknown.

If there are any other pundits out there with information on the wherabouts or derivation of this word, please let me know!

[A pundit is a learned person. Hindu]
