Pronunciation

Forms

OK, also written O.K. and okay.[2][1]

Etymology

It is borrowed from English OK, American English, first recorded in Boston in 1839 as an abbreviation of “all correct” playfully spelled “oll korrect”, part of a fashion for such jokes on the east coast of the United States (“O.W.” for “all right”, spelled “oll wright”).[2] Taken up in election campaigns in New York, it was reinterpreted as the initials of “Old Kinderhook”, after a Democratic candidate from Kinderhook whose supporters formed an “OK Club”, and opponents of General Andrew Jackson said it showed his poor spelling; it quickly became widely known.[2]

In French it is pronounced by spelling out the English letters.[2]

Earliest recorded meaning

It is first found in French in 1869, in the journal L'Ingénieur, describing the laying of the Atlantic cable: tout était O.K. (“all was in order”).[2]

Semantic evolution

The interjection marking agreement is recorded in 1931, in Luc Durtain's Captain O.K..[2] The spelling okay is used by Gabrielle Roy in 1945, and the noun meaning “approval” is found in Quebec writing (son okay final).[2]
