Etymology
The word 'chamber' entered English in the 13th century from the Old French 'chambre', meaning a room, especially a private one in a house. The Old French term derived from the Latin 'camera', which originally signified a vaulted room or an arched ceiling. This Latin word itself was borrowed from the Ancient Greek 'kamára', meaning anything with an arched cover, such as a vault or a covered wagon. The core logic of the word's evolution traces back to this idea of a covered, enclosed space, which broadened from an architectural feature to denote any private or specialized room, and later to any enclosed compartment.
Analysis
The word 'chamber' is a simplex loanword from French. It cannot be meaningfully segmented into smaller, independent morphemes using its modern English spelling.
Examples
The jury retired to the deliberation chamber.
