Think of the semi-colon as a flashing red light. You must stop, but can usually go on quickly. Semi-colons are used in two ways:

1. In a sentence, a semi-colon can join two complete sentences that are related and make them into one sentence.

"Ask not what your country can do for you; ask what you can do for your country."

2. Semi-colons are used to help emphasize the division between items that themselves include commas.

I invited Fred Flintstone, from Bedrock; Mork, from Ork; and Roseanne, from Langford, Illinois, to our Halloween party.

People flock to Love, Texas; Cupid Falls, Minnesota; Valentine, Idaho; and Heart, Montana to get their special postmarks for Valentine's Day.
