An intensive pronoun is a type of pronoun that adds emphasis to a statement by referring back to the subject of the sentence. It is almost identical to a reflexive pronoun, but their functions differ. Intensive pronouns are used to add emphasis to the subject or antecedent of the sentence. They are defined as pronouns that end in "self" or "selves" and place emphasis on their antecedent. For example, "I did it myself" is a sentence that uses an intensive pronoun to emphasize that nobody else did it. Intensive pronouns are different from reflexive pronouns because they function as an adverbial or adnominal modifier, not as an argument of a verb. Both intensive and reflexive pronouns make reference to an antecedent.

To differentiate an intensive pronoun from a reflexive pronoun, remove it from the sentence. If the sentence still makes sense, it is an intensive pronoun. If the sentence no longer makes sense when the pronoun is removed, it is a reflexive pronoun. Intensive pronouns can appear directly after the antecedent or later in the sentence, and they can also appear before the antecedent, separated from it with a comma.

Examples of intensive pronouns include "myself," "yourself," "himself," "herself," "itself," "ourselves," "yourselves," and "themselves".
