1. Start with a noun or pronoun. This will be the main subject of your sentence.
2. Follow it with a comma.
3. Add a word or phrase that renames or describes the noun/pronoun. This is your appositive.
4. End with another comma.
Example:
* My dog, a fluffy golden retriever named Max, loves to chase squirrels.
In this sentence:
* My dog is the main subject.
* a fluffy golden retriever named Max is the appositive, which renames "my dog."
Here are a few more examples:
* The Empire State Building, a towering skyscraper in New York City, is a famous landmark.
* My favorite author, Stephen King, writes suspenseful novels.
* She brought her favorite dessert, a chocolate cake with raspberry frosting, to the party.
Remember:
* Appositives can be single words or phrases.
* They are always set off by commas.
* They should provide additional information about the noun/pronoun they describe.
