What Are Reflexive Pronouns?
They are pronouns 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. They are usually used when the object of a sentence is the same as the subject.
1. When the subject and object in a sentence are the same.
They have to go there and remove the car themselves. (subject is they, object is themselves)
2. As the object of a preposition, when the subject and the object are the same.
The troublesome delinquents cause problems to themselves. (subject is
troublesome delinquents, object is themselves, preposition is to)
3. When you want to emphasise the subject.
I drew this masterpiece myself. (no one else helped me)
