An appositive phrase refers to a noun or a pronoun that identifies or rename another noun or pronoun; it gives more information about that noun or pronoun. An appositive together with its modifier is called an appositive phrase. An appositive phrase is said to be non- essential when it adds information to a sentence whose meaning is already clear. Non-essential appositives are usually set off by a coma.
