Etymologies

from The American Heritage® Dictionary of the English Language, 4th Edition

[Middle English castel, from Old English and from Norman French, both from Latin castellum, diminutive of castrum; see kes- in Indo-European roots.]

from Wiktionary, Creative Commons Attribution/Share-Alike License

From Middle English castle, castel, from Old English castel, castell, cæstel, ċeastel ("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"). 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  (hēþjō, "chamber"), Old English heaþor ("restraint, confinement, enclosure, prison"). See also casino, cassock.

  • "Castles were good for keeping out the enemy, but there were few other benefits from living in a large damp pile of stones, and as times grew more peaceful from around the 16th century, the landed gentry started to build fine residences - known simply as 'country houses'."
