There may be more stories about the origin of "OK" than there are uses for it: it comes from the Haitian port "Aux Cayes," from Louisiana French au quai, from a Puerto Rican rum labeled "Aux Quais," from German alles korrekt or Ober-Kommando, from Chocktaw okeh, from Scots och aye, from Wolof waw kay, from Greek olla kalla, from Latin omnes korrecta. Other stories attribute it to bakers stamping their initials on biscuits, or shipbuilders marking wood for "outer keel," or Civil War soldiers carrying signs for "zero killed."
What is the origin of the word 'OK'?
There have been numerous attempts to explain the emergence of this expression, which seems to have swept into popular use in the US during the mid-19th century. Most of them are pure speculation.....
.....The only other theory with at least a degree of plausibility is that the term originated among Black slaves of West African origin, and represents a word meaning 'all right, yes indeed' in various West African languages. Unfortunately, historical evidence enabling the origin of this expression to be finally and firmly established may be hard to unearth.
