Word History

Etymology

borrowed from French châssis "window sash, cold frame, frame holding cloth to be painted or embroidered, supporting frame of a motor vehicle," going back to Old French chasiz "window frame" from casse (Anglo-Norman & Norman dialect) "reliquary" (Middle French chasse "frame, mount") + -iz, denominal collective suffix, often of things linked or intertwined, of uncertain origin — more at case entry 2

Note: To judge by the derivative chasiz, attested already in the twelfth century (Roman d'Énéas), the meaning "frame" of casse/chasse is older than its first Middle French attestation in the fourteenth century. Presumably the Latin source capsa had developed more than one sense, all subsumable under the meaning "something holding or enclosing" in Gallo-Romance.
