An intensive pronoun is a type of pronoun used to emphasize a noun or another pronoun. It typically ends in "-self" or "-selves," such as myself, yourself, himself, herself, itself, ourselves, and themselves. Intensive pronouns are not necessary for the sentence's meaning; they simply add emphasis to the subject. For example, in the sentence "I made the cake myself," the word myself emphasizes that the speaker personally made the cake. Intensive pronouns can be used with any noun or pronoun to highlight the subject's involvement or effort in an action.
