         Rule #1  
          Commas and Transition Words and 
          Phrases 
         | 
    
  
   
  
  Rule: 
    Use a comma to separate a transition word or phrase 
    from the rest of the sentence. A transition word connects a preceding 
    sentence or a paragraph. Words such as 
    first, 
    moreover, and for 
    example help the reader understand the flow of ideas. 
    
  
  If the transition word or phrase comes 
    at the beginning of the sentence, use a comma to separate it from the sentence. 
    
           Example: 
    
               
      For example, we read many 
    illustration essays.
  
  If the transition word or phrase comes 
    in the middle of the sentence, use two commas to separate it from the sentence.
             Example:
                  We 
    read, for example, many illustration essays. 
    
    
  
  If the transition word comes between 
    two sentences, use a semicolon before the transition and a comma after it.
             Example: 
    
                 The 
    instructor writes many sentences on the board; for 
    example, in one class she wrote fifty sentences on the board.
