Here's what you need to know:
* Subject pronouns replace nouns that perform the action of a verb in a sentence.
* They are the core of a sentence and tell you who or what is doing the action.
Examples of subject pronouns:
* I am going to the store.
* You are a great friend.
* He is my brother.
* She loves to dance.
* It is raining outside.
* We are going on vacation.
* They are playing soccer.
Remember:
* Use the correct subject pronoun depending on the number and person of the noun it replaces.
* Make sure the pronoun agrees with the verb in number (singular or plural).
