"Cast away" is a phrasal verb predominantly used in informal contexts, often found in storytelling or casual conversation rather than in formal discourse. It typically means to discard or get rid of something or someone, implying that the discarded item is of little value or unwanted. This term can also evoke contexts of being stranded or isolated, as in being ''cast away'' on a deserted island, linking it to adventure narratives and tales of survival. While "cast away" can be used metaphorically to describe feelings of abandonment, it remains versatile in describing physical actions of throwing something aside. In such usages, it carries a connotation of finality or intentional separation. The phrasal verb is commonly associated with its adjectival form "castaway," which often describes a person stranded alone in an uninhabited place.
