Английский Этимологический словарь - remark (v.)

- 1633, modeled on Fr. remarquer "to mark, note, heed," from M.Fr. re-, intensive prefix + marquer "to mark," probably from a Gmc. source, cf. O.H.G. marchon "to delimit" (see mark). Originally "to mark out, distinguish" (a sense preserved in remarkable, 1604); meaning "make a comment" is c.1700, from notion of "make a verbal observation" or "call attention to specific points." The noun is from 1654.
