• Commas: The second set of rules…

     

    1.  Use commas to set off introductory elements at the beginning of sentences.

                EX: If they want to win, athletes must practice daily.

                EX: Wanting to win, athletes practice daily.

     

    2.  Use commas to set off appositives and other nonessential (extra) information.

                EX: My house, a traditional colonial, needs some remodeling.

    EX: The managers, who sought higher profits, hired temporary workers to replace full-time staff.

                EX: Bob Jones, checking tickets at the counter, asked for a form of identification.

     

    3. Do NOT use a comma to set off essential information that is needed to understand the meaning of the sentence.

    EX: Managers who are seeking higher profits must hire temporary workers to replace full-time staff. 

    EX: The person checking tickets at the counter asked for a form of identification.
