glaive (v.) Look up glaive at
late 13c., used in Middle English of various weapons, especially ones with a long shaft ending in a point or an attached blade, from Old French glaive "lance, spear, sword" (12c.), also figuratively used for "violent death," probably from Latin gladius "sword" (see gladiator); influenced by Latin clava "knotty branch, cudgel, club," related to clavus "nail."
