Usage

And is OK in the dictionary? OK is a word. The term OK may also be spelled okay. There is confusion as to whether OK is a word because it is informal, looks like an acronym, and is spelled with all capital letters. However, none of these elements disqualify OK from being a valid word.

Etymology

Origin of OK

Initials of a facetious folk phonetic spelling, i.e., oll or orl korrect representing all correct, first attested in Boston, Massachusetts, in 1839, then used in 1840 by Democrat partisans of Martin Van Buren during his election campaign, who allegedly named their organization, the O.K. Club, in allusion to the initials of Old Kinderhook, Van Buren's nickname, derived from his birthplace, Kinderhook, New York
