1633, "to mark out, distinguish" 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). Original sense preserved in remarkable (1604); meaning "make a comment" is first attested c.1694, from notion of "make a verbal observation" or "call attention to specific points." The noun is from 1654.
