The phrasal verb "come on" is predominantly used in informal contexts, though certain formal scenarios may accommodate it, such as in the arts or certain motivational or persuasive speeches. In general usage, "come on" functions in multiple contexts: as an encouragement or exhortation (e.g., "Come on, you can do it"), a way to urge action or increase speed (e.g., "Come on, we're going to be late"), an expression of disbelief or frustration (e.g., "Oh, come on, that can't be true"), or an indication for equipment or machinery to start functioning (e.g., "The lights come on at dusk"). Additionally, it serves in theatrical or performative contexts when someone makes an entrance (e.g., "He comes on stage"), and in social scenarios as an attempt to flirt or subtly pursue someone romantically (e.g., "He tried to come on to her at the party"). This versatility allows it to be one of the more commonly leveraged phrasal verbs in English, easily adapted depending on tone and situation.
