Word History: The pejorative nature of the term fool is strengthened by a knowledge of its etymology. Its source, the Latin word follis, meant “a bag or sack, a large inflated ball, a pair of bellows.” Users of the word in Late Latin, however, saw a resemblance between the bellows or the inflated ball and a person who was what we would call “a windbag” or “an airhead.” The word, which passed into English by way of French, is first recorded in English in a work written around the beginning of the 13th century with the sense “a foolish, stupid, or ignorant person.”
