French Imperative Mood

The ability to give clear instructions, make polite requests, or offer encouragement is fundamental to everyday communication. Mastering the French imperative mood allows you to do just that—it is the verb form used exclusively for giving commands, making suggestions, and offering advice. While it may seem straightforward, its unique rules for verb conjugation and pronoun placement are essential for sounding both competent and courteous in French.

Forming the Regular Imperative

The French imperative is unique because you use it only with three subject pronouns: tu (informal singular "you"), nous ( "we" or "let's"), and vous (formal singular or plural "you"). To form it, you typically take the corresponding forms of the present tense and simply drop the subject pronoun. The verb then stands alone as the command.

Let's use the regular -er verb parler (to speak) as our model:

• For tu: Present tense is tu parles. Drop the tu, and the command is Parles ! (Speak!)
• For nous: Present tense is nous parlons. Drop the nous, and the command is Parlons ! (Let's speak!)
• For vous: Present tense is vous parlez. Drop the vous, and the command is Parlez ! (Speak!)

This pattern holds true for all regular -ir and -re verbs as well. For example, with finir (to finish): Finis ! (Finish!), Finissons ! (Let's finish!), Finissez ! (Finish!). With attendre (to wait): Attends ! (Wait!), Attendons ! (Let's wait!), Attendez ! (Wait!).

The Crucial -ER Verb Exception for "Tu"

Here is the first key exception you must memorize. For all regular -er verbs (and the verb aller, which is irregular but ends in -er), the final -s is dropped in the tu form of the imperative. This is a common source of errors for learners.

• Parler: The present tense is tu parles. The correct imperative is Parle ! (not Parles).
• Donner (to give): Donne ! (Give!)
• Aller (to go): Va ! (Go!)

Think of it this way: in the tu command for -er verbs, the verb form often sounds identical to the "il/elle" form in the present tense (il parle, elle donne). This rule does not apply to nous or vous forms, and it does not apply to -ir or -re verbs in the tu form (you keep the -s in Finis ! and Attends !).

Essential Irregular Imperatives

A small group of very common verbs have completely irregular imperative forms that you must learn by heart. Fortunately, the list is short but vital:

1. Être (to be): Sois ! (tu), Soyons ! (nous), Soyez ! (vous)

• Sois prudent ! (Be careful!)

1. Avoir (to have): Aie ! (tu), Ayons ! (nous), Ayez ! (vous)

• Aie confiance ! (Have confidence!)

1. Savoir (to know): Sache ! (tu), Sachons ! (nous), Sachez ! (vous)

• Sache que je t'aime. (Know that I love you.)

1. Vouloir (to want): Veuille ! (tu), Veuillons ! (nous), Veuillez ! (vous)

• The veuillez form is exceptionally important as it is the standard for polite requests, equivalent to "please." Veuillez patienter. (Please wait.)

Notice that for these verbs, you cannot simply take the present tense and drop the subject pronoun; you must use these specific forms.

Pronoun Placement: Affirmative vs. Negative Commands

This is the most nuanced part of using the imperative. The placement of object pronouns (me, te, le, lui, nous, vous, leur, y, en) changes dramatically depending on whether your command is affirmative (do something) or negative (don't do something).

In affirmative commands, the pronouns follow the verb and are connected by a hyphen. Furthermore, the order changes: me and te become moi and toi, but they revert to m' and t' before en or y.

• Donne-le-moi ! (Give it to me!)
• Parlez-lui ! (Speak to him/her!)
• Achètes-en ! (Buy some!) [Remember the -s is kept on -er verbs before en and y]
• Allons-y ! (Let's go!)

In negative commands (using ne...pas), the pronoun placement returns to its normal position: before the verb.

• Ne me le donne pas ! (Don't give it to me!)
• Ne lui parlez pas ! (Don't speak to him/her!)
• N'en achète pas ! (Don't buy any.)
• N'y allons pas ! (Let's not go.)

A handy mental trick is that a negative imperative is structured just like a normal negative sentence, but without the subject pronoun.

Common Pitfalls

1. Adding the Subject Pronoun: The most basic error is including the tu, nous, or vous. The imperative verb stands alone. Incorrect: Tu parle ! Correct: Parle !
2. Forgetting the -S Drop for -ER Verbs: Using Parles ! instead of Parle ! is a very common mistake. Remember the rule: for tu commands with -er verbs, drop the final -s.
3. Misplacing Pronouns in Affirmative Commands: Placing the pronoun before the verb in an affirmative command is incorrect. Incorrect: Le-moi donne ! Correct: Donne-le-moi !
4. Using the Wrong Irregular Form: Trying to conjugate être or avoir regularly in the imperative will lead to errors like Êtes ! or Aves !. You must memorize the short list of irregulars: sois, aie, sache, veuille.

Summary

• The imperative mood is used for commands, suggestions, and advice, formed from the tu, nous, and vous present tense forms by dropping the subject pronoun.
• A critical exception: for all -er verbs in the tu command, you must drop the final -s (e.g., Parle !).
• Four key verbs have irregular imperative forms you must memorize: être (sois, soyons, soyez), avoir (aie, ayons, ayez), savoir (sache, sachons, sachez), and vouloir (veuille, veuillons, veuillez).
• Pronoun placement changes completely based on command type. In affirmative commands, pronouns follow the verb with a hyphen (Donne-le-lui). In negative commands, pronouns precede the verb (Ne le lui donne pas).
