Word Origin and History for closed (1 of 5)

The Latin word might be from the possible PIE root *klau- "hook, peg, crooked or forked branch" (used as a bar or bolt in primitive structures); cf. Latin clavis "key," clavus "nail," claustrum "bar, bolt, barrier," claustra "dam, wall, barricade, stronghold;" Greek kleidos (genitive) "bar, bolt, key," klobos "cage;" Old Irish clo "nail," Middle Irish clithar "hedge, fence;" Old Church Slavonic ključi "hook, key," ključiti "shut;" Lithuanian kliuti "to catch, be caught on," kliaudziu "check, hinder," kliuvu "clasp, hang;" Old High German sliozan "shut," German schließen "to shut," Schlüssel "key."

Intransitive meaning "draw together, come together" is from 1550s, hence the idea in military verbal phrase close ranks (mid-17c.), later with figurative extensions.
