Answer

Okay is a term of approval or assent, often written as OK, O.K., ok, okay, okee, okey, okie, okey day or more informally as simply kay, k or kk. Sometimes used with other words, as in quotokey, dokeyquot. When used to describe the quality of a thing, it denotes acceptability. However, its usage can also be strongly approving as with most slang, its usage is determined by context.brThe historical record shows that O.K. appeared as an abbreviation for quotoll korrectquot a conscious misspelling of quotall correctquot in Boston newspapers in , and was reinterpreted as quotOld Kinderhookquot in the United States presidential election. Because it is a recent word born of word play, and because it is so widely used, O.K. has also invited many folk etymologies. These competing theories are not supported by the historical written record, except in that folk and joke etymologies influenced the true history of the word. Since the th century, the word has spread around the world, the okay spelling of it first appearing in British writing in the s. Spelled out in full in the th century, okay has come to be in everyday use among English speakers, and borrowed by nonEnglish speakers. Occasionally a humorous form okey dokey or okey doke is used, as well as Aok.
