Etymology
The term 'foreign-body' is a transparent compound formed in Modern English from two distinct roots. 'Foreign' traces back to the Latin forās, meaning "outside," which evolved through Old French to signify something originating from or characteristic of another place. 'Body' originates from the Old English bodig, referring to the physical structure of a person or animal. The compound logically combines these concepts: a 'body' (a physical entity) that is 'foreign' (external in origin), creating a precise medical and technical term for an external object lodged where it does not belong. This construction exemplifies how English builds specific terminology by combining native and borrowed elements with clear, literal meanings.
