Compounding Sentences
by
Compounding Verbs

      When two sentences in a row have the same meaningful subject, they can usually be combined by deleting the subject of the second sentence and attaching its verb to the verb in the first sentence with a coordinating conjunction ("and," "or," or "but."):

Bill often went to the hobby shop. He bought most of his trains there.
Bill often went to the hobby shop and bought most of his trains there.
You may even find three or more sentences that share the same subject such that you can combine several sentences into one:
Sarah wanted to go to the game. But she caught a cold. She had to stay home.
Sarah wanted to go to the game, but caught a cold, and had to stay home.
When you combine sentences in this way, do not forget to adjust the punctuation and capitalization to fit the revised sentence.
