| Rule #4 Commas and Noun of Direct Address  | 
    
Rule: Use a comma to separate a noun of direct address from the rest of the sentence.
A noun of direct address names the person who is receiving the information.
..........Example: John, you should call your mother.
      The noun of 
    direct address is John.
  
The noun can move in the sentence.
..........Examples: You should, John, call your mother.
..... You should call your mother, John....... ........
*Writing Tip:
Do not confuse a noun of direct address with the subject of a sentence.
Example: Noun of direct address- Doctor, call the nurse.
Subject - The doctor called the nurse.
