yes: Mary shot John with her pistol; he died a few weeks later.
yes: Mary shot John with her pistol. He died a few weeks later.
yes: Mary shot John with her pistol, and he died a few weeks later.

CQ Check quotation
Double check to make sure the quotation is accurate.

DP Double predicate
When you have two verbs with only one subject, donít put a comma in between the verbs.

yes: John ate and drank.

no: Their greatest contribution, the invention of the flying buttress.

MM Mixed-up modifier
You have used a modifying phrase inaccurately. Most likely, you have broken the rule that states that a participle phrase at the beginning of a sentence modifies the subject of that sentence.

no: I saw my motherís house flying over Washington.
yes: Flying over Washington, I saw my motherís house.

no: Mary, who was a spy carried a pistol.
no: Mary who was a spy, carried a pistol.

RO Run-on sentence
If two complete sentences are joined with a conjunction, you need a comma before the conjunction.
