Question

What is the appositive phrase in this sentence? The flavors she chose were black licorice, cotton candy, and penuche, a kind of maple fudge.

Answer 1

An appositive phrase is a noun or noun phrase that renames another noun right beside it.

For example; Our house, a brick bungalow, is on Oak Street.

a brick bungalow would be the appositive phrase.

In your case:

The flavors she chose were black licorice, cotton candy, and penuche, a kind of maple fudge.

The sentence could have just been: The flavors she chose were a kind of maple fudge.
But instead they added "black licorice, cotton candy, and penuche"
Therefore that is your answer. :)
