You are indeed describing an appositive, which is a noun or noun phrase that renames or provides additional information about another noun next to it. Appositives are often set off by commas when they are non-restrictive, meaning that the sentence would still make sense without the appositive.

For example:
- My brother, **a talented musician**, is coming to visit.

In this sentence, "a talented musician" is an appositive that gives more information about "my brother". If the appositive is restrictive (essential to the meaning of the sentence), it typically doesn't use commas. For example:

- The author **J.K. Rowling** is well-known for her Harry Potter series.

Here, "J.K. Rowling" is essential to identify which author is being referred to, so it is not set off by commas.

Is there anything specific you would like to know or explore further about appositives?
