What does a Colon look like?
When should I use a Colon?
A colon is used before a list or an explanation that is proceeded by an independent clause or a shortened sentence. "Think of the colon as the gate, inviting one to go on," 2.
A colon is really helpful if you are making a list, such as a to do list. It can also be helpful if you are giving ideas about a topic.
Examples:
