APPLYING THE RULE

Correct Punctuation between Independent Clauses

3.         The correct punctuation for joining two sentences is an "assisted" comma.

           a semicolon                             ;           [comma "assisted" by a period]

           a comma with FANBOYS     ,and     [comma "assisted" by a coordinate conjunction*]

           sentence          Jerry went to a party ; he wrecked his car coming home.

           sentence          This exam is finished ,so you must turn in your papers.

           sentence          Everyone wants to go ; however, we don't have any money.

           *Note: Use the word "FANBOYS" as a memory aid to help to remember these conjunctions.

                 For                And                     Nor                    But                     Or                Yet                 So
           (because)      (in addition)    (negative choice)     (contrast)     (positive choice)    (however)     (result)

4.        Study these correctly joined sentences. Each sentence is really two short sentences joined
           to make one compound sentence. The punctuation occurs at the spot where the second
           sentence joins the first. The punctuation "sticks" the sentences together.

           sentence          Maybe we should leave now; it's getting very late.
           sentence          Our team has won the game, so we are the new champs.
           sentence          Christmas will be here soon; therefore, we should begin our shopping.
           sentence          Christmas will be here soon; we should, therefore, begin our shopping.
