Imperative verbs are verbs that create an imperative sentence (i.e. a sentence that gives an order or command). When reading an imperative sentence, 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.
