The document discusses the imperative form for giving commands in English. The imperative uses the base form of the verb. Affirmative commands do not use a subject, while negative commands use "don't". The imperative with "let's" is used to give commands or suggestions that include the speaker. It follows the same structure as the regular imperative, using the base form for affirmatives and "let's not" for negatives.
