Here's a breakdown:
* Subject: The person or thing performing the action in the sentence.
* Pronoun: A word that stands in for a noun.
Examples:
* She went to the store. ("She" replaces the noun "Mary" as the subject)
* I love pizza. ("I" replaces the noun "John" as the subject)
* They are playing in the park. ("They" replaces the noun "The children" as the subject)
Subject pronouns in English:
* Singular: I, you, he, she, it
* Plural: We, you, they
Important Note: Subject pronouns are not used as objects of verbs or prepositions. For that, you would use object pronouns (me, you, him, her, it, us, them).
