Origin of the word Signature

  1. 1534, a kind of document in Scottish law, from M.Fr. signature (16c.), from M.L. signatura "sign," in classical L. "the matrix of a seal," from signatus, pp. of signare "to mark, sign" (see sign). Meaning "one's own name written in one's own hand" is from 1580, replacing sign-manual (1428) in this sense. more
