Reflexive sounds like reflection, the image in the mirror that bounces back at you. A reflexive pronoun reflects back to the subject. A reflexive pronoun can be used as the direct object, indirect object, or object of a preposition in a sentence.
Intensive is like intense. Something intense is very strong. An intensive pronoun emphasizes a preceding noun, often the noun immediately before the pronoun. It is not necessary to the sentence.
These pronouns are reflexive or intensive depending on their use in a sentence.
Reflexive: The puppy saw itself in the mirror.
Itself is the direct object in the sentence. The pronoun refers back to the subject. The puppy saw the puppy in the mirror.
Intensive: The queen herself gave the knight the award. The queen gave the knight the award herself.
Herself refers to the queen.
Do not use reflexive pronouns instead of subject or object pronouns.
