When you dash, you run a short distance very quickly. If you forget your lunch in the morning, you might try to dash home, grab it, and dash back to school.
When your dog chases your cat, they dash around the house — you can call this sprint itself a dash. You could say, "I won the 50-yard dash!" or "Our trip to the mall was just a mad dash, because we were late for the movie."When you use the punctuation mark known as a dash, you write a horizontal line ( — ) to mark a pause, a change, or an omitted word.
