The pronoun 'himself' is a reflexive pronoun, a word that  takes the place of a singular noun for a male, used to 'reflect'  back to its antecedent.   Example: Dad got uâ¦p and made himself some breakfast.    The pronoun 'himself' is also an intensive pronoun, used to  emphasize its antecedent.
This applies especially to third-person personal pronouns, and to relative pronouns. For example, in the sentence That poor man looks as if he needs a new coat, the antecedent of the pronoun he is the noun phrase that poor man. The adjective associated with pronoun is pronominal. A pronominal is also a word or phrase that acts as a pronoun.
