What is a reflexive pronoun?
A reflexive pronoun is a pronoun such as “myself” that’s used to refer back to the subject of the sentence. You should use one instead of an object pronoun when the subject and object of the sentence are the same—i.e., when the subject is acting on themselves.
For example, in the sentence “She trusts herself to do this,” the person doing the trusting (“she”) is the same person who is being trusted (“herself”). If you instead said “She trusts her to do this,” “her” would be taken to refer to a different person.
The English reflexive pronouns are myself, ourselves, yourself, yourselves, himself, herself, itself, themselves, and oneself. They can also be used as intensive pronouns.
