cast-off

The compound "cast-off" is a straightforward combination of two ancient English elements. The verb "cast," with its roots in Old Norse, carries the primary sense of throwing or shedding. The particle "off," from Old English, universally denotes separation or departure. When combined, the literal meaning "to throw away" evolved naturally into its modern figurative senses. It first described discarded objects, particularly old clothes, and later extended metaphorically to describe people or things rejected by society or a group, perfectly encapsulating the action of being thrown aside.

Structure: cast (throw) + off (away) - cast: From Old Norse 'kasta' (to throw), of uncertain ultimate origin. Functions as the core verb meaning "to throw or project." - off: From Old English 'of', 'off', meaning "away, from, or down from." Functions as an adverbial particle indicating separation or removal.
