copacetic

Etymology
Stephen Goranson says "there is good reason to think that Irving Bacheller invented the word [with spelling copasetic] for a fictional character with a private vocabulary in his best-selling and later-serialized 1919 book about Abraham Lincoln in Illinois, A Man for the Ages", and its currency increased by use in the 1920 song "At the New Jump Steady Ball". Alternatively, it has been speculated that it may have originated among African Americans in the Southern US in the late 19th or early 20th century, perhaps specifically in the jargon of Bill "Bojangles" Robinson, who certainly helped popularize it in any case. Many hypotheses about its origin (etymon) exist, all lacking supporting evidence:


 * That it derives from 🇨🇬 /.
 * That it derives from a word * used by 🇨🇬 speakers in New York.
 * That it derives from 🇨🇬 — if the Chinook Jargon term is not itself derived from English.
 * The common suggestion that the term derives from Hebrew has been rejected, as has the fanciful suggestion that it derives from criminals' observation that they could go about their business because "the cop is on the settee".

Adjective

 * 1)  Fine, excellent, OK, in excellent order.
