More specifically, it's a reflexive pronoun. Reflexive pronouns refer back to the subject of the sentence.
Here's a breakdown:
* Pronoun: A word that replaces a noun or noun phrase.
* Reflexive: A type of pronoun that refers back to the subject of the sentence. It typically ends in "-self" or "-selves" (e.g., myself, yourself, himself, herself, itself, ourselves, yourselves, themselves).
Examples:
* The dog licked itself clean. (Here, "itself" refers back to the subject "dog")
* She prepared herself for the presentation. (Here, "herself" refers back to the subject "She")
