Direct object uses the nouns and pronouns in objective case?

That's correct! Direct objects are the nouns or pronouns that receive the action of the verb. They are always in the objective case.

Here's a breakdown:

* Nouns: The objective case of a noun is the same as its nominative case (e.g., "dog," "car," "house").

* Pronouns: Pronouns have different forms for the subjective and objective case. Here's a table showing some examples:

| Subjective Case | Objective Case |

|---|---|

| I | me |

| You | you |

| He | him |

| She | her |

| It | it |

| We | us |

| They | them |

Example:

* Subject: The boy threw the ball.

* Direct Object: The boy threw the ball.

Here, "boy" is the subject (performing the action) and "ball" is the direct object (receiving the action). Both are in the objective case.
