More about copacetic
Copacetic first appears in the generation before World War II, in 1919 to be exact. It is a thoroughly American piece of slang, and all the citations of the word come from American writers. Perhaps foreigners avoided copacetic because of all its variant spellings, which include copa, copasetic, copasetty, copesette(e), copissettic, copus, kopacetic, kopasetic, kopasetee…. Many slang terms have no reliable etymology, and copacetic is within that happy group. Some of the more fanciful, not to say outrageous or just plain nutty etymologies for copacetic include; 1) Chinook jargon copasenee “everything is satisfactory (along the waterways of Washington State)”; 2) the excruciating phrase “the cop is on the settee” (i.e., he’s not paying attention), which transmogrified into copacetic and was supposedly used by American gangsters; or 3) an Italian word, but unknown in standard Italian or in any of its many dialects. Bill “Bojangles” Robinson claimed to have coined copacetic (not likely), but he did popularize copacetic in his vaudeville acts, radio programs, and movies he made with Shirley Temple in the 1930s.
