"Commenced" is a term that means to begin or start something. It is often used in formal contexts, such as in legal documents, project management, or official announcements. For example, when a new construction project is approved, it may be stated that work has "commenced" on the site. In everyday language, "commenced" can refer to the start of various activities, such as a meeting, a class, or an event. For instance, a school year may commence in September, marking the beginning of a new academic period for students and teachers.
