Identify the correct pronoun: The boy cried himself to sleep.

Pronouns are used as noun substitutes in English grammar. Pronouns are classified into eight types: indefinite, personal, reflexive, possessive, demonstrative, relative, interrogative, and emphatic. In the above line, we can see that the subject's behavior reflects on the subject itself. As a result, this is a case of reflexive pronouns. 'I purchased myself a new ring' is another such scenario. Emphatic pronouns are employed when reflexive pronouns are utilized to emphasize something or someone.
