Variations
Whether this word is printed as OK, Ok, ok, okay, or O.K. is a matter normally resolved in the style manual for the publication involved. Dictionaries and style guides such as The Chicago Manual of Style and The New York Times Manual of Style and Usage provide no consensus. Whilst most variants have descended from the root "OK", "okay" predominates in edited English as it permits easier modification (e.g. by pluralising).
