The phrasal verb "plan on" is predominantly used in informal and conversational settings, but it can also appear in more formal contexts when the tone is relatively casual or when a speaker wants to convey a sense of relatability. It indicates an intention or expectation regarding a future action and is often followed by a gerund, for example, "plan on attending" or "plan on buying." This construct is typically used to convey one's intentions or future actions in conversations about routines, schedules, or events. "Plan on" can be interchangeable with more formal phrases like "intend to" or "anticipate," but it often carries a slightly softer and more tentative connotation, suggesting the speaker's intentions may be subject to change based on circumstances.
