What is an Appositive Phrase?
An appositive phrase is a word or phrase that renames the noun. It makes positively sure you know what the writer is talking about. We say that an appositive is "in apposition" to the noun, which means that it's next to the noun.
EX. My aunt, a nurse, is moving to South Carolina. In this sentence, a nurse is appositive to my aunt because both are the same person in this context.
Appositive phrases are separated by commas in the sentence which allows the phrase to add emphasis to the noun. This also allows the appositive phrase to be removed, without changing the meaning of the sentence.
EX. My aunt is moving to South Carolina is still understood after taking out the appositive phrase (a nurse).
