chassis
UK: ˈʃæsi | US: ˈʃæsi
n. the framework of a vehicle, supporting its structure and mechanical components.
n. (electronics) the base frame of a device or machine.
The word "chassis" originates from the Old French "châssis," meaning "frame" or "support," derived from the Latin "capsa" (box or case). It entered English in the 17th century, initially referring to window frames before evolving to describe vehicle frameworks in the automotive era. The morpheme "chass" preserves the French root, while "-is" acts as a nominal suffix, reflecting its adaptation into English.
