Here's why:
* Direct objects answer the question "what?" or "whom?" after the verb. For example:
* "The dog chased the ball." (What did the dog chase? The ball.)
* "She called him." (Whom did she call? Him.)
* Direct objects are essential to understanding the complete action of the verb. They tell us who or what is being acted upon.
* Direct objects are usually found after transitive verbs. Transitive verbs require a direct object to complete their meaning.
