An imperative is a command or instruction given to someone to do (or not do) something. In the examples provided, "Fly north" and "Swim in the river" are imperatives.

To make the negative form of an imperative, we add "don't" before the base verb. For example, "Don't fly north" and "Don't swim in the river" are negative imperatives.
