Etymology

From Middle English closen (“to close, enclose”), partly continuing (in altered form) earlier Middle English clusen (“to close”) from Old English clȳsan (“to close, shut”); compare beclose, foreclose, etc.), and partly derived from Middle English clos (“close, shut up, confined, secret”, adjective), from Old French clos (“close, confined”, adjective), from Latin clausus (“shut up”, past participle), from claudere (“to bar, block, close, enclose, bring an end to, confine”), from Proto-Indo-European *kleh₂w- (“key, hook, nail”), related to Latin clāvis (“key, deadbolt, bar”), clāvus (“nail, peg”), claustrum (“bar, bolt, barrier”), claustra (“dam, wall, barricade, stronghold”). Cognate with Ancient Greek κλείς (kleís, “bar, bolt, key”), German schließen (“to close, conclude, lock”), Dutch sluiten (“to close, conclude, lock”). Partially replaced Old English lūcan (“to close, lock, enclose”), (whence English lock). Doublet of clause.
