Copacetic is first recorded in the early 1900s. Although it may sound Latinate, its origin is unknown. Proposed languages of origin include Chinook, Italian, Louisiana French, and Hebrew, but none of the origin stories are particularly convincing.

The first attested use of the word comes from Irving Bacheller’s 1919 book about Abraham Lincoln, A Man for the Ages (in which he spelled it copasetic). It further entered the public consciousness through the Prohibition-era song “At the New Jump Steady Ball,” whose lyrics include the line “Copasetic was the password for one and all, at the new jump steady ball.” By the 60s and 70s, when it reemerged as popular slang, the common spelling became copacetic, as it is generally spelled today.
