What is a subject pornoun?

A subject pronoun is a type of pronoun that performs the action of the verb in a sentence. It typically replaces the noun that acts as the subject, making sentences clearer and less repetitive. Common subject pronouns in English include "I," "you," "he," "she," "it," "we," and "they." For example, in the sentence "She runs fast," "she" is the subject pronoun that indicates who is performing the action.
