Imperatives are used to issue commands. They use the infinitive of verbs (dropping the word "to"); in the first person plural ("we"), the infinitive is preceded by "let's" (or: "let us"):
The negative imperative is formed by placing "don't" (or "do not") before the imperative form; in the first person plural one uses "let's not" (or "let us not") :
The imperative has no effect on the word order of the rest of the sentence.
