What is the class of pronouns which turns the action back on the subject?

The group of pronouns that turn the action back on the subject are the reflexive pronouns.

A reflexive pronoun 'reflects back' to its antecedent.

The reflexive pronouns are: myself, yourself, himself, herself, itself, ourselves, yourselves, themselves.

Example: Dad got up and made himself some breakfast.

Note: The reflexive pronouns also function as intensive pronouns, used to emphasize its antecedent.

Example: Dad himself got up and made some breakfast.
