The phrasal verb "stop by" is predominantly used in informal contexts, making it less common in formal speech or writing. Generally, it is employed to describe a brief visit to a place, often without a planned schedule or announcement. One might use "stop by" when visiting a friend's house, a store, or an office for a short period, usually to accomplish a quick task, pick up something, or simply say hello. The expression conveys a sense of casualness and spontaneity, implying no extensive commitment to the duration or purpose of the visit. Its informality is indicated by its frequent use in conversational English, casual emails, or informal invitations among friends and acquaintances. Despite its casual nature, it is understood and accepted widely due to its clear and straightforward implication.
