A sentence has a comma splice or comma fault when a comma is used to separate two main clauses. The resultant sentence is called a run-on sentence. Here is an example of a run-on sentence.
“Red is an energy colour, it is a colour of fire and hot days.”
There are three ways to correct this run-on sentence.
Red is an energy colour; it is a colour of fire and hot days.
Red is an energy colour. It is a colour of fire and hot days.
Red is an energy colour: it is a colour of fire and hot days.
If you want to separate and connect the two clauses, use a semicolon. If you want to end the sentence, use a period. If you want to introduce an explanation, use a colon.
