The phrase "has finished" is a verb form that indicates the completion of an action or task. It is often used in the present perfect tense, which connects past actions to the present moment. For example, when someone says, "She has finished her homework," it means that the homework is now complete. This expression can apply to various contexts, such as work, projects, or activities. For instance, if a student has finished reading a book, it signifies that they have completed the reading process. The phrase emphasizes the result of an action rather than the action itself.
