What type of pronouns refer back to the noun or pronoun used as the subject of the sentence?

Reflexive pronouns are the type of pronouns that refer back to the noun or pronoun used as the subject of the sentence. They are formed by adding "-self" or "-selves" to certain personal pronouns. For example, in the sentence "She taught herself how to play the piano," "herself" refers back to "she," indicating that the subject performed the action on itself.

Reflexive pronouns include words like "myself," "yourself," "himself," "herself," "itself," "ourselves," "yourselves," and "themselves." They are used to emphasize the subject or indicate that the subject performs and receives the action of the verb.

Other types of pronouns do not serve this specific function. Possessive pronouns indicate ownership, relative pronouns introduce relative clauses, and interrogative pronouns are used to ask questions. Thus, understanding the role of reflexive pronouns within sentence structure is essential for effective communication and proper writing.
