Explanation

The word “Act” can mean doing something on purpose. When someone acts, they are not just thinking or talking — they are doing something, like helping a friend or making a decision. It also means behaving in a certain way, such as acting polite or angry. In entertainment, act means to perform in a play, movie, or show. It can also be a noun, like a part of a play or a single thing someone does.
