The phrasal verb "set about" is moderately used in both formal and informal contexts, though it may lean slightly towards formal or written English. It generally means to begin dealing with a task, project, or problem; often implying a certain determination or methodical approach. For example, one might say, "They set about cleaning the house early in the morning," or "The committee set about addressing the policy issues." It is commonly used when describing the initiation of an action, especially when the task requires effort or persistence. The verb phrase aids in emphasizing that an activity has not only begun but is being undertaken with intent or purpose. It's less frequently heard in casual speech compared to simpler alternatives like "started" or "began," but is well recognized and understood in both spoken and written communications.
