Usage: Use "starring" only when describing an actor who holds the lead role in a film, play, or show, rather than simply appearing prominently. Do not confuse this adjective with phrases like "featuring," which can apply to supporting cast members as well.
Derived from Middle English starren, which comes from Old French estorner (to startle), the verb originally meant to distract or divert attention rather than its modern sense of featuring as a main performer. The current meaning evolved in the 19th century through the metaphorical extension of "being the star" or central figure.
