Writing & Grammar: Commas With Who

by Jennie Ruby 

 

The words who, that, and which introduce interrupting clauses into a sentence. Those interruptions may be essential (no commas) or nonessential (commas before and after). Here are examples of each.

Essential: People who wear glasses should not throw punches.

Nonessential: Our waiter, who was the son of the restaurant owner, spilled a glass of punch right on my head.

Although the word who can be used either with or without commas, the word which requires commas and the word that does not. After making the comma decision, make sure the correct word is used.

Challenge: Commas with who, that, and which

The hapless writer of these sentences (based on a real text) has evidently been told always to use a comma before who. See if you can help him out.
