Answer:
Appositive Phrase
Step-by-step explanation:
Appositive Phrase
An appositive is a noun or a noun phrase that renames the noun next to it. It serves the purpose of adding information about another noun. For example, consider the phrase "The boy raced ahead to the finish line. " Adding an appositive noun phrase could result in "The boy, an avid sprinter, raced ahead to the finish line."
The sentence is still complete without the appositive. However, adding the appositive (an avid sprinter) presents more information about the other noun (boy).
