shadowed

Shadowed is the past participle of shadow. It functions as both a verb form and an adjective. As a verb, to shadow someone means to follow them closely and secretly in order to observe or monitor them. In its physical sense, to shadow something is to cast a shadow over it or to place it in shade, reducing light. As an adjective, shadowed describes something that has been obscured by shadow or that is hidden or overshadowed—literally (a shadowed area) or figuratively (a shadowed history, a shadowed intention). In literary and journalistic usage, a person or event may be described as shadowed when it is surrounded by suspicion or uncertainty.

In computing and information contexts, shadowing describes a situation where one identifier in a local scope hides another with the same name in an outer scope; the inner declaration shadows the outer one. This is often referred to as variable shadowing. In professional settings, shadowing can also refer to a learning arrangement in which a novice follows a more experienced person to gain firsthand experience and knowledge about a role.

Etymology and history: shadowed derives from the noun shadow, whose roots lie in Old English sceadu. The verb sense to shadow emerged in Middle English, with the figurative sense of obscurity or overshadowing developing over time. The term remains versatile across genres, continually expanding to describe physical shading, covert following, and metaphorical obscurity.
