UK: ˈstænd ɪn | US: ˈstænd ɪn
n. a substitute or temporary replacement for someone, especially in a performance or job.
n. (film/theater) a person who replaces an actor during rehearsals or for technical preparations.
The term "stand-in" emerged in the early 20th century, primarily in the film industry. It combines "stand" (from Old English standan, meaning "to occupy a place") and "in" (indicating involvement or substitution). The logic reflects someone "standing in" another's place temporarily, originally for lighting or camera setup, later generalized to any substitute role.
