type of pointed sword, 1550s, from French rapière, from espee rapiere "long, pointed two-edged sword" (late 15c.), in which the adjective is of uncertain origin; perhaps it is from a derisive use of raspiere "poker, scraper." Dutch, Danish rapier, German Rappier are from French.
Originally a long, pointed, two-edged sword with a guard for the hand, used, especially in 16c.-17c., for either cutting or thrusting; later, in fencing, a light, sharp-pointed sword for thrusting.
