1. Appositive Phrases
An appositive phrase renames or explains a noun in a sentence.
An appositive phrase is normally set off by commas. (The exception to this rule would be when the appositive is only a single word. Then it does not need to have commas around it.)
Appositives are noun phrases.
App.
Ex. The man, a doctor, said he would be with us in a minute.
Ex. My cat Charlotte is ornery!

2. Diagramming Appositive Phrases
An appositive is diagrammed in parenthesis after the noun it renames.
The only word that goes into the parenthesis is the actual word that renames. Any other words are modifiers and would be placed beneath the word in parenthesis.
