Tense guide
Imperative
Give commands, instructions, suggestions, warnings, or invitations directly to someone.
When to use it
Use it when speaking to tu, nous, or vous: écoute, allons-y, regardez. The subject pronoun is normally omitted.
How to recognise it
The verb often starts the sentence and has no subject before it: viens, prenez, finissons.
How to form it
Use the tu, nous, and vous forms of the present. For many -er verbs, the tu form drops the final -s: tu parles -> parle.
A simple rule
With object pronouns, word order changes in positive commands: donne-le, parle-moi; but negative commands keep the normal order: ne me parle pas.
Examples
Finissons le travail.
Let us finish the work.
