Explanation:

The appositive phrases are phrases that include appositive or nouns that use other nouns or pronouns to deliver a message. There are two types of appositive phrases: essential or inessential. The factor that differentiates them is the essential one they employ appositive to provide information necessary to identify the pronoun.
