OK, What's the World's Best Known Word? Okay,That May Be It.

In observance of Columbus Day, The Committee Room asks you to consider how often you say OK. This little Americanism is probably the world's most used word. In OK: The Improbable Story of America's Greatest Word Allan Metcalf writes "[T]hese two simple letters (or four, if you use its genteel alter ego okay) anchor our agreements, confirm our understandings, and choreograph the dance of everyday life...OK is the most amazing invention in the history of American English."

Among English speakers, at least, OK's versatility is astounding. It is put to work an adjective ("The council deemed the project OK"), a noun ("The council gave its OK to the project"), a verb ("The council OK'd the project"), occasionally as an adverb ("The council took the criticism OK"), and most frequently as a throat clearing interjection ("The council member began the discussion with 'OK, let's talk about the project'"). Depending upon tone and context OK can convey a positive or neutral assessment. Partnered with a minimizer as such "just" or "only" or "merely" it becomes negative.
