Word Origin & History

O.E. of, unstressed form of æf (prep., adv.) "away, away from," from P.Gmc. *af- (cf. O.N. af, O.Fris. af, of "of," Du. af "off, down," Ger. ab "off, from, down"), from PIE *apo- "off, away" (see apo-). Primary sense in O.E. was still "away," but shifted in M.E. with use
of the word to translate L. de, ex, and especially O.Fr. de, which had come to be the substitute for the genitive case. "Of shares with another word of the same length, as, the evil glory of being accessory to more crimes against grammar than any other." [Fowler]
