Do you want to say the same thing twice? Use an appositive, which is a noun or a pronoun that refers to exactly the same person or thing as the noun or pronoun that precedes it in the sentence. Check out these examples:

Noel, the boy who won a car on the game show, fainted dead away.

Nadia, the valedictorian, decided to drive a truck instead of going to Stanford.

Do you see the pairs of matching ideas? Noel and the boy who won a car on a game show are the same. Nadia and the valedictorian are too. The second half of each pair is the appositive.

Pronouns can serve as appositives, usually when you have two or more people or things to talk about. Here are some examples:

Those of us who don't like horror movies, Elaine and I, never saw Friday the 13th.

The new employees, David and she, weren't in the meeting.
