What Is an Appositive?

An appositive is a noun or noun phrase that renames or explains another noun right next to it. It helps to add detail or clarify meaning. Both the noun and the appositive refer to the same person or thing.

Basic Example

In this sentence:

Carol, my boss, just called a meeting.

“My boss” is the appositive. It gives extra information about Carol.

Key Features of Appositives

• An appositive follows the noun it identifies or explains.
• It can be a single word or a full phrase.
• The sentence still makes sense if you remove the appositive.

Commas with Appositives

Use commas when the appositive adds extra (nonessential) information. This is called a nonrestrictive appositive.

Sara, a student, raised her hand.

Here, “a student” is not necessary to identify who Sara is — it just gives extra detail.

Do not use commas when the appositive is essential to understand the noun. This is called a restrictive appositive.

My friend Jake is visiting from London.

Here, “Jake” tells us which friend — the name is essential. No commas are used.
