Appositives
Noun or noun phrase that tells you more about a nearby noun or pronoun
Punctuation Rules
- If the appositive is not essential to the meaning of the sentence but is an aside or parenthetical remark, then the writer should use punctuation to set off the appositive
-
If the appositive occurs before the noun it describes, set it off with a comma
-
If the appositive occurs in the middle of the sentence, set it off on both sides with the same punctuation - either dashes or commas
- Dashes: more striking form of punctuation - tend to add emphasis to the appositive
- If the apposite occurs at the end of the sentence, you can set it off with a comma, a dash (for extra emphasis), or a colon
- The colon is necessary if the appositive following the sentence consists of a list of items
