"Reflexive pronouns<span> are </span>pronouns<span> that refer back to the subject of the sentence or clause. They either end in –self, as in the singular form, or –selves as in the plural form. " "</span>Intensive pronouns<span> use reflexive </span>pronouns<span> to add emphasis to the subject of the sentence. The </span>intensive<span>/reflexive </span>pronouns<span> are myself, yourself, himself, herself, itself, ourselves, yourselves and themselves. "
"</span><span> an </span>intensive pronoun<span> is different from a </span>reflexive<span>, because the </span>pronoun<span> can be removed without altering the </span>meaning<span> of the sentence." </span><span>
For example, in #1 it's: "yourselves" and I believe it's intensive.
