From Middle English castle, castel, from Old English castel, castell (“a town, village, castle”), borrowed from Late Latin castellum (“small camp, fort”), diminutive of Latin castrum (“camp, fort, citadel, stronghold”), possibly from Proto-Indo-European *kat- (“hut, shed”). Parallel borrowings (from Late Latin or Old French) are Scots castel, castell (“castle”), West Frisian kastiel (“castle”), Dutch kasteel (“castle”), German Kastell (“castle”), Danish kastel (“citadel”), Swedish kastell (“citadel”), Icelandic kastali (“castle”), Welsh castell. The Middle English word was reinforced by Anglo-Norman/Old Northern French castel, itself from Late Latin castellum (“small camp, fort”) (compare modern French château from Old French chastel). If Latin castrum (“camp, fort, citadel, stronghold”) is from Proto-Indo-European *kat- (“hut, shed”), Latin casa (“cottage, hut”) is related. Possibly related also to Gothic 𐌷𐌴𐌸𐌾𐍉 (hēþjō, “chamber”), Old English heaþor (“restraint, confinement, enclosure, prison”). See also casino, cassock.

  1. A large building that is fortified and contains many defences; in previous ages often inhabited by a nobleman or king.
