chamber (English)

Where does "chamber" come from?

The English noun 'chamber' comes from Middle English 'chambre'[1], which was borrowed from Old French 'chambre'[1]. The Old French term traces back to Latin 'camera'[4], which itself derives from Ancient Greek 'καμάρα'[1] meaning 'vaulted chamber'[1]. This ancient Greek term carried meanings related to arched covers and vaults[2], ultimately connecting back to earlier Indo-European roots.

• The ancient Greek term kamara is alternatively suggested by Kroonen to derive from Proto-Indo-European *h₂éḱmō meaning heavenly vault or anvil, rather than an Iranian borrowing. [5] [6]
