Is the pronoun in sentence reflexive intensive both or neither Joan helped herself to more pie.?

The pronoun in the sentence "Joan helped herself to more pie" is reflexive.

Here's why:

* Reflexive pronouns refer back to the subject of the sentence, indicating the action is being performed by the subject on themselves. In this case, "herself" refers back to "Joan".

* Intensive pronouns emphasize the subject of the sentence, but they are not essential to the grammatical structure. For example, "Joan herself made the pie" - the sentence would still make sense without "herself".

Therefore, the pronoun "herself" in this sentence is reflexive, not intensive.
