A quick guide to using the colon. A colon is made up of two dots, one placed above the other. One common use of the colon is to introduce a list of items. For example: To make the perfect jam sandwich you need three things: some bread, butter and strawberry jam. Three items are listed in the sentence above.
Rule: Use the semicolon if you have two independent clauses connected without a conjunction. Example: I have painted the house; I still need to sand the floors. Rule: Also use the semicolon when you already have commas within a sentence for smaller separations, and you need the semicolon to show bigger separations. Example: We had a reunion with family from Salt Lake City, Utah; Los Angeles, California; and Albany, New York.
