Here's how to recognize an appositive:
* It's always a noun or noun phrase.
* It's set off by commas, dashes, or parentheses.
* It renames or identifies the noun it follows.
Examples:
* My sister, Sarah, is a doctor. (Sarah renames My sister)
* The car, a sleek black Mercedes, sped down the highway. (A sleek black Mercedes renames car)
* He introduced me to his best friend, John. (John renames his best friend)
* The city, a bustling metropolis, never sleeps. (A bustling metropolis renames city)
Why use appositives?
* To add clarity and detail: They provide more information about the noun they're describing.
* To emphasize a point: By placing a noun phrase after another, it can draw attention to it.
* To add variety to your writing: They can help to break up long sentences and make them more engaging.
Important notes:
* Not all phrases set off by commas are appositives. For example, "The dog, which is a golden retriever, barked loudly" does not have an appositive.
* An appositive can be a single word or a longer phrase.
