Subject Pronouns and Object Pronouns: Useful Rules & Usage

How to use subject pronouns and object pronouns correctly? Sentences would get boring, tedious, and difficult to read if we had to use the same words over and over again. Thankfully, we have pronouns to help make our sentences become clearer, less awkward, and smoother. They prevent us from repeating the same nouns over and over.

What exactly is a pronoun? It is a word that takes the place of a noun. It replaces and performs the same actions as the noun in a sentence. A reminder that a noun is a person, place, thing, or idea.

What Are Subject Pronouns and Object Pronouns?

Two types of pronouns are subject and object pronouns. Deciding which one of them to use is dependent on the subject or action in the sentence. Subject pronouns are not the same as object pronouns. The subject pronoun will replace the subject in a sentence. The object pronoun will replace the object in the sentence. How do we do that? Once we have looked for the subject and the action in the sentence, we can determine the pronoun to replace it.

The subject of a sentence is the noun which is doing the action.

The object of a sentence is the noun that is having the action done to it.

This is shown in the following sentences.

  • Bryce wrote a letter

Bryce is the subject. He is performing the action.
Letter is the object. It is having the action performed to it.

  • Students (subject) ate their lunch (object).
  • The clown (subject) juggled three balls (object)
