Rule #4: Extra Information

Use commas to set off clauses, phrases, and words that are not essential to the meaning of the sentence.

Hint: if you read the sentence without the words in between the commas, the sentence should still make sense.

Example: Dr. Yang, a pediatrician, completed his check-up.

Example: I drove the car, which belonged to my brother, to the mechanic.
