What are the three main parts of a basic sentence?

The three main parts of a basic sentence are the subject, the verb, and the object. The subject indicates who or what the sentence is about, the verb expresses the action or state of being, and the object receives the action of the verb. For example, in the sentence "The cat (subject) chased (verb) the mouse (object)," each part plays a distinct role in conveying the complete thought.
