The phrasal verb "stand by" is predominantly used in informal contexts but can also appear in formal settings, particularly in written communication. In informal speech, it often implies waiting in readiness (e.g., "Please stand by for instructions"), offering support or remaining loyal ("I will stand by you"), or maintaining one's previous decisions or opinions ("The company stands by its claims"). In more formal contexts, it is used in similar ways to indicate readiness or adherence to a previously stated position. "Stand by" is versatile and commonly appears in contexts involving customer service, emergency broadcasts, and interpersonal support scenarios. Additionally, "stand by" may also refer to a person or a thing that is ready to serve as a backup or alternative, such as 'a standby generator.' Its adaptability and clarity make it a useful and widely recognized phrasal verb across different discourse types.
