Where the word okay used first?

Answer 1

1839, only Survivor of a slang fad in Boston and New York c.1838-9 for abbreviations of common phrases with deliberate, jocular misspellings (cf. K.G. for "no go," as if spelled "know go"); in this case, "oll korrect." Further popularized by use as an election slogan by the O.K. Club, New York boosters of Democratic president Martin Van Buren's 1840 re-election bid, in allusion to his nickname Old Kinderhook, from his birth in the N.Y. village of Kinderhook. Van Buren lost, the word stuck, in part because it filled a need for a quick way to write an approval on a document, bill, etc. The noun is first attested 1841; the verb 1888. Spelled out as okeh, 1919, by Woodrow Wilson, on assumption that it represented Choctaw okeh "it is so" (a theory which lacks historical documentation); this was ousted quickly by okay after the appearance of that form in 1929. Okey-doke is student slang first attested 1932. Greek immigrants to America who returned home early 20c. having picked up U.S. speech mannerisms were known in Greece as okay-boys, among other things.

Answer 2

The word "okay" is believed to have originated in the United States in the 1830s as a slang term, derived from the initials of "oll korrect," a humorous misspelling of "all correct." Its first documented use was in a Boston newspaper in 1839.
