Imperative verbs are verbs which create an imperative sentence, i.e. a sentence that gives an order. It will always sound like the speaker is bossing someone around. Imperative verbs don’t leave room for questions or discussion, even if the sentence has a polite tone.
Use the root form of the verb to create the imperative.
