Spanish informal commands explained with affirmative and negative forms

Introduction

Informal spoken Spanish relies heavily on commands. Understanding how to form and use informal commands — both affirmative and negative — is essential for everyday conversation. This guide explains the rules, shows clear examples, and highlights common pitfalls to help beginner and intermediate learners speak with confidence.

What are informal commands?

Informal commands are verbs used to tell someone you address as tú or vosotros to do or not do something. In many Latin American countries, tú is the norm for informal singular commands, while in Spain both tú and vosotros appear. This article focuses mainly on tú forms for simplicity, with notes on vosotros and usted when relevant.

Why learn informal commands

Everyday interactions—giving directions, offering instructions, making requests, or giving advice—use informal commands. They are shorter and more direct than full sentences with subjunctive structures, so native speakers use them frequently. Learning them improves listening comprehension and speaking fluency.

Formation of affirmative informal commands (tú)

The affirmative informal command for tú uses the third-person singular form of the present indicative. In other words, take the él/ella/usted form of the present tense and use it as the command.

Examples with regular verbs:

hablar → habla
comer → come
vivir → vive

So to tell a friend to speak, eat, or live, you say habla, come, vive. This is straightforward for regular verbs, but irregular verbs require memorization.

Common irregular affirmative tú commands

Some very common verbs have irregular affirmative tú commands. These must be learned individually because they do not follow the regular pattern.

decir → di
hacer → haz
ir → ve
poner → pon
salir → sal
ser → sé
tener → ten
venir → ven

Example sentences:

Di la verdad.
Haz la tarea.
Ve al supermercado.
Sé paciente.

Affirmative commands with pronouns

When attaching object pronouns to affirmative commands, they attach directly to the end of the verb, forming one word. If the resulting word has more than one syllable or the stress changes, add an accent to preserve pronunciation.

Examples:

dímelo → di + me + lo → dime + lo → dímelo (accent added)
hazlo → haz + lo → hazlo (no accent needed)
dame → da + me → dame (note that dar has irregular command da)

Placement rule: attach pronouns to the affirmative command: dímelo, cómpralo, tráemelo.

Formation of negative informal commands (tú)

Negative informal commands for tú use the present subjunctive. The structure: take the yo form of the present indicative, drop the -o, and add the opposite tú ending: -es for -ar verbs and -as for -er and -ir verbs.

Steps with examples:

hablar: yo hablo → drop o → habl- → add -es → no hables
comer: yo como → com- → add -as → no comas
vivir: yo vivo → viv- → add -as → no vivas

Negative commands always place the word no before the verb and pronouns go before the verb, not attached.

Examples with pronouns:

No me lo digas.
No lo compres.
No te vayas.

Irregular negative tú commands

Some verbs have irregularities in the subjunctive stem, so the negative tú command will reflect that. For example:

dar → no des
estar → no estés
ir → no vayas
saber → no sepas
ser → no seas

Examples:

No seas tonto.
No vayas allí.
No estés tarde.

Comparing affirmative and negative forms

A key point for learners is that many verbs have different forms for affirmative and negative tú commands. The affirmative uses él/ella indicative; the negative uses tú subjunctive. This often means completely different words.

Examples:

habla (affirmative) vs no hables (negative)
di (affirmative) vs no digas (negative)
ve (affirmative) vs no vayas (negative)

Because the forms differ, learners must memorize both forms rather than assuming just to add no.

Why the difference matters

The difference arises from Spanish grammar history and the need to mark prohibitions differently. The subjunctive in negative commands reflects the speaker’s desire for the action not to happen and is more hesitant or hypothetical. For learners, treat this as a rule to follow rather than a conceptual hurdle: affirmative = third-person indicative, negative = tú subjunctive.

Vosotros and usted commands: brief notes

In Spain, you will encounter vosotros informal commands. Affirmative vosotros commands are formed by replacing the -r of the infinitive with -d: hablar → hablad, comer → comed, vivir → vivid. Pronouns attach to affirmative vosotros verbs: venidme aquí becomes venidme aquí (with accent adjustments as needed).

Negative vosotros commands use the vosotros present subjunctive: no habléis, no comáis, no viváis. These mirror the negative tú pattern but use vosotros endings.

Formal commands for usted and ustedes use the present subjunctive: hable, hablen, coma, coman. These are used for polite or plural formal situations.

More examples in context

Short dialogs and sentences help make the rules concrete. Observe placement of no and pronouns, and watch irregulars.

At a café:
Camarero: ¿Qué quieres?
Amigo: Dame un café, por favor.
Camarero: Aquí tienes.
Amigo: No pongas azúcar, gracias.

Giving directions:
Persona A: ¿Cómo llego a la estación?
Persona B: Ve todo recto. Luego, toma la segunda calle a la izquierda. No te pierdas.

Parent to child:
Padre: Ten cuidado con la calle.
Padre: No corras en la piscina.

Common mistakes and how to avoid them

1. Using the infinitive instead of the command. Incorrect: no hablar. Correct: no hables. Remember negative commands use subjunctive tú.

2. Forgetting pronoun placement. Incorrect: damelo. Correct: dámelo. For affirmative commands attach pronouns; for negative commands place them before: no me lo des.

3. Mixing affirmative and negative forms. Incorrect: no di eso. Correct: no digas eso. Learn irregulars in both forms.

4. Assuming vosotros is common in Latin America. In most of Latin America, tú and ustedes are used instead; reserve vosotros for Spain or Andalusian contexts.

Usage and cultural notes

Informal commands can express friendliness, urgency, or rudeness depending on tone, context, and relationship. In many Spanish-speaking cultures, using tú commands with someone you do not know or with elders can be perceived as impolite. When in doubt, use the formal usted command or a polite request such as por favor ¿puede usted…?

Also, regional variations exist. In many parts of Central and South America, voseo replaces tú with vos. Voseo has its own command forms: affirmative vos commands usually use the present indicative without the final s for some verbs: comer → comé, venir → vení. If you plan to travel or live in a voseo area, study local forms.

Quick cheat sheet

Affirmative tú: use él/ella present indicative. Example: habla, come, vive.
Negative tú: use tú present subjunctive with no before the verb. Example: no hables, no comas, no vivas.
Attach pronouns to affirmative commands: dímelo, tráelo.
Put pronouns before negative commands: no me lo digas, no lo traigas.

Final tips for practice

Listen to native speakers in conversations, TV shows, and podcasts and pay attention to commands. Mimic intonation and pronoun placement. Create simple task lists using commands to describe daily routines: Levántate, desayuna, sal de casa. Use flashcards for irregular affirmative commands and subjunctive stems for negative forms. Over time, patterns will become automatic.

Conclusion

Informal commands are a vital part of conversational Spanish. Learn the two different formations—affirmative using the third-person present and negative using the tú subjunctive—memorize common irregulars, and practice pronoun placement. Note regional differences like vosotros and voseo, and choose formal or informal forms appropriately. With focused practice you will use informal commands naturally and confidently.
