It explains that a subject is the person or thing performing the action of the sentence. A verb expresses the action or state of being. Objects receive the action of verbs. Complements add more meaning about the subject or object. Adverbials modify verbs or add circumstances. Examples are given for each element to illustrate their usage in simple sentences.
