In grammar, an appositive is a word, phrase, or clause that supports another word, phrase, or clause by describing or modifying the other word, phrase, or clause. Although nouns and noun phrases most often perform the function, pronouns can also function as appositives. Examples of pronouns as appositives include the following:
That man, him, stole my wallet. (personal pronoun)
Those children, him and her, are mine. (personal pronoun)
The winners are these two cakes, hers and his. (personal pronoun)
A man brought a package for the team leader, you. (personal pronoun)
The file, that, is what you need to finish the project. (demonstrative pronoun)
Twelve of the cakes, these, go to the Obi-wan party. (demonstrative pronoun)
The use of pronouns as appositives is more frequent in speech than in writing.
