Pronouns
A pronoun is a word used to take the place of a noun, which can be a person, place, animal, or thing. We use a pronoun to avoid repeating a noun that has already been mentioned. A pronoun usually comes after the noun it replaces.
A pronoun may come before a noun that it replaces. In such an order, it has to be made clear so that a reader or listener knows which noun the pronoun takes the place of.
Ex: She, Jenny, is my elder sister.
(She is a pronoun that replaces the noun Jenny, which is also known as an appositive.)
the only millionaire in the village, he is also the oldest.
