Commas with Appositives
When a sentence contains a word, phrase, or clause
that gives information about the subject noun, that word,
phrase, or clause may or may not need to be set off by
commas. Commas are used if the information in the
word, phrase, or clause is interesting but not essential to
the meaning of the sentence. Commas are not used
when the information in the word, phrase, or clause
must be included because the sentence would be
unclear or incorrect without it.
Which sentence is written in compliance with the
guidelines for commas?
