Don't Do It! (Negative Tú Commands)
Grammar Rule in 30 Seconds
To tell a friend 'don't' do something, use the 'yo' form, drop the 'o', and add the opposite ending.
- For -AR verbs, use the -es ending (e.g., No hables).
- For -ER/-IR verbs, use the -as ending (e.g., No comas).
- Always put the word 'No' before the verb.
Overview
In Spanish, telling someone not to do something using the informal tú form involves a distinct grammatical mechanism. Unlike affirmative tú commands, which often resemble the third-person singular of the present indicative (Habla, Come), negative tú commands utilize the Present Subjunctive. This shift is not arbitrary; it reflects a fundamental linguistic principle where prohibitions and expressions of desire or influence are channeled through the subjunctive mood.
For A2 learners, mastering this difference is essential for expressing warnings, prohibitions, and strong advice naturally to friends, family, and peers. It also serves as a foundational step toward understanding the broader application of the subjunctive, a cornerstone of Spanish grammar. Recognizing and correctly applying this rule prevents miscommunication and significantly enhances fluency in informal settings.
How This Grammar Works
tú commands lies in the inherent nature of the message conveyed. The Indicative mood is used for facts, certainty, and objective statements, such as Tú corres (You run). Conversely, the Subjunctive mood communicates subjectivity, including desires, wishes, emotions, doubts, and critically, influence or command over another's actions.No corras (Don't run), you are not merely negating the action of running. Instead, you are expressing a strong desire, prohibition, or instruction for the listener to refrain from that action. This act of influencing or directing another's behavior naturally aligns with the subjunctive's function.No abras la puerta (Don't open the door) is an expression of will to prevent the door from being opened.Formation Pattern
tú commands precisely involves a three-step process rooted in the Present Subjunctive. This method, often termed the "Yo-Drop-Swap" technique, starts with the yo form of the present indicative and modifies it to yield the correct subjunctive command. This systematic approach ensures accuracy for most verbs.
yo form of the verb in the Present Indicative.
hablar (to speak) → yo hablo
comer (to eat) → yo como
escribir (to write) → yo escribo
-o ending.
hablo → habl-
como → com-
escribo → escrib-
tú subjunctive ending.
-ar in the infinitive, add -es.
-er or -ir in the infinitive, add -as.
Yo Form (Indicative) | Step 2: Drop -o (Stem) | Step 3: Add "Opposite" Ending | Negative Tú Command |
hablar | hablo | habl- | -es | no hables |
comprar | compro | compr- | -es | no compres |
comer | como | com- | -as | no comas |
beber | bebo | beb- | -as | no bebas |
escribir | escribo | escrib- | -as | no escribas |
vivir | vivo | viv- | -as | no vivas |
yo forms or are entirely irregular in the subjunctive, necessitating memorization.
Yo Forms: Any irregularity in the present indicative yo form (beyond simply dropping -o) directly translates to the subjunctive stem.
tener (to have) → yo tengo → no tengas (Don't have)
venir (to come) → yo vengo → no vengas (Don't come)
hacer (to do/make) → yo hago → no hagas (Don't do/make)
salir (to leave) → yo salgo → no salgas (Don't leave)
decir (to say/tell) → yo digo → no digas (Don't say/tell)
tú commands, the crucial ones are Dar, Ir, Saber, Estar, and Ser.
Tú Command |
dar | no des |
ir | no vayas |
saber | no sepas |
estar | no estés |
ser | no seas |
-car, -gar, and -zar undergo spelling changes in the subjunctive to maintain phonetic consistency. This is a sound-driven rule, not an arbitrary irregularity.
Yo Form | Stem | Tú Subjunctive (Spelling Change) | Negative Tú Command |
tocar | toco | toc- | toques (c → qu before e) | no toques |
llegar | llego | lleg- | llegues (g → gu before e) | no llegues |
empezar | empiezo | empiez-| empieces (z → c before e) | no empieces |
e → ie, o → ue, e → i) are preserved in the subjunctive. The stem change occurs before applying the "opposite" ending.
cerrar (e → ie): yo cierro → no cierres (Don't close)
volver (o → ue): yo vuelvo → no vuelvas (Don't return)
pedir (e → i): yo pido → no pidas (Don't ask)
dormir (o → ue, o → u): yo duermo → no duermas (Don't sleep)
no, nunca, jamás, tampoco) always precedes the conjugated verb in a negative tú command.
When To Use It
tú commands are employed in informal contexts to prohibit actions, issue warnings, or offer strong advice. They are indispensable for communicating directly with individuals you address with tú, such as friends, family, children, or close associates. Their usage spans a range of everyday situations.- Prohibitions and Warnings: To explicitly forbid an action or caution against danger.
No cruces la calle sin mirar.(Don't cross the street without looking.)No toques el horno, está caliente.(Don't touch the oven, it's hot.)No conduzcas cansado.(Don't drive tired.)
- Advice and Suggestions: To provide firm guidance or recommend avoiding a particular action for someone's benefit.
No te preocupes por el examen, has estudiado mucho.(Don't worry about the exam, you've studied a lot.)No comas tan rápido.(Don't eat so fast.)No dejes tu pasaporte en el coche.(Don't leave your passport in the car.)
- Setting Boundaries: Clearly communicating what you prefer someone not to do in a personal interaction.
No me hables en ese tono, por favor.(Don't speak to me in that tone, please.)No me llames tan tarde.(Don't call me so late.)
- Requests for Inaction: Asking someone to refrain from a specific action.
No te vayas aún, quédate un rato más.(Don't leave yet, stay a bit longer.)No cierres la puerta, por favor.(Don't close the door, please.)
tú, these commands are reserved for familiar relationships. Using them in formal settings with strangers, superiors, or elders would be considered impolite; in such cases, usted or ustedes commands are appropriate. The negative tú command is thus a vital linguistic tool for navigating interactions within your intimate social circle, enabling clear, direct communication of limits, warnings, and heartfelt advice.Common Mistakes
tú commands. Identifying these common errors and understanding their grammatical basis is crucial for developing accuracy.- Confusing Affirmative and Negative Forms: The most common error is attempting to use the affirmative
túcommand form withno. - Incorrect:
*No habla.(Intending "Don't speak.") - Correct:
No hables.(hablaris an -ar verb, requiring-esin the subjunctivetúform.)
tú are distinct. The former often uses the present indicative's third-person singular, while the latter exclusively uses the present subjunctive tú form.- Omitting the Final
-s: Thetúform of the present subjunctive (and consequently the negativetúcommand) invariably ends in-s. Learners sometimes drop this-sdue to its absence in affirmativetúcommands (¡Habla!). - Incorrect:
*No hable.(Without-s, this becomes theustedcommand form.) - Correct:
No hables.
-s can mistakenly elevate the politeness level or alter the intended recipient, leading to communication breakdowns.- Incorrect Pronoun Placement: This is a critical grammatical difference between affirmative and negative commands.
- Affirmative Commands: Object pronouns (direct, indirect, reflexive) attach directly to the end of the verb.
Cómelo.(Eat it.)Dímelo.(Tell it to me.)- Negative Commands: Object pronouns always precede the conjugated verb, positioned between
no(or another negative word) and the verb. - Incorrect:
*No comaslo. - Correct:
No lo comas.(Don't eat it.) - Incorrect:
*No digasme. - Correct:
No me digas.(Don't tell me.)
- Failure to Apply Stem Changes or Irregularities: Any stem change or irregular
yoform in the present indicative carries over into the subjunctive and, by extension, into the negative command. Reverting to the infinitive stem is a common mistake. - Verb
pensar(e → ie): - Incorrect:
*No pensas. - Correct:
No pienses.(Don't think.) - Verb
dormir(o → ue): - Incorrect:
*No dormas. - Correct:
No duermas.(Don't sleep.)
- Overlooking Spelling Changes for Phonetics: Verbs ending in
-car,-gar, or-zarrequire spelling adjustments (ctoqu,gtogu,ztoc) to preserve their original hardk, hardg, orssounds, respectively. - Verb
tocar:*No tocas.→No toques.(Don't touch.) - Verb
llegar:*No llegas.→No llegues.(Don't arrive.)
- Confusing with Simple Negative Statements: A negative command (
No hables) differs functionally from a simple negative statement (No hablas). No hablas español.(You don't speak Spanish.) – A statement of fact (Indicative).No hables español aquí.(Don't speak Spanish here.) – A command or prohibition (Subjunctive).
tú commands, ensuring their intentions are clearly conveyed.Real Conversations
To truly grasp negative tú commands, it is crucial to observe their usage in authentic, daily conversations. These examples demonstrate how native speakers apply these commands across various informal settings, from quick exchanges to casual spoken advice, always reflecting a familiar relationship between speakers.
Scenario 1
- Amigo 1: Acabo de ver el final de la serie, ¡qué sorpresa! (I just saw the end of the series, what a surprise!)
- Amigo 2: ¡No me lo cuentes! Todavía no lo he visto. (Don't tell me it! I haven't seen it yet.)
- No me lo cuentes (from contar) is a direct request to prevent spoiling the show. Both me (indirect object) and lo (direct object) precede the verb.
Scenario 2
- Madre: Hijo, ¡no toques la estufa! Está muy caliente. (Son, don't touch the stove! It's very hot.)
- Hijo: ¿Por qué, mamá? (Why, Mom?)
- Madre: Porque no quiero que te quemes. (Because I don't want you to burn yourself.)
- No toques (from tocar, with a spelling change) is an urgent warning. The indirect command (no quiero que te quemes) reinforces the underlying desire for safety.
Scenario 3
- Amiga 1: Estoy muy nerviosa por la entrevista de mañana. (I'm very nervous about tomorrow's interview.)
- Amiga 2: Entiendo, pero no estés tan ansiosa. Has preparado todo. Y no pienses en lo peor. (I understand, but don't be so anxious. You've prepared everything. And don't think about the worst.)
- No estés (irregular estar) and no pienses (stem-changing pensar) are comforting pieces of advice, encouraging the friend to avoid anxiety and negative thoughts.
Scenario 4
- Compañero 1: ¿Podemos dejar las luces encendidas por la noche? (Can we leave the lights on at night?)
- Compañero 2: No, por favor. No dejes las luces encendidas cuando salgas, gasta mucha energía. (No, please. Don't leave the lights on when you leave, it wastes a lot of energy.)
- No dejes (from dejar) is a clear boundary-setting request concerning energy consumption.
These examples underscore that negative tú commands are not mere grammatical constructs but integral parts of daily Spanish interaction, used fluently by native speakers to manage social dynamics, provide care, and express personal preferences within informal relationships.
Quick FAQ
no + affirmative command? It seems simpler.Spanish grammar differentiates between stating a fact (indicative) and expressing influence, desire, or prohibition (subjunctive). Affirmative tú commands are direct orders of action. Negative tú commands, conversely, are instructions for inaction, which linguistically falls under the realm of influencing behavior. Thus, they require the subjunctive mood. Using the incorrect indicative form (*no habla) would be grammatically incorrect and would not convey the intended prohibitive force.
no? Are there other negative words?While no is the most common, other negative adverbs or phrases can also precede and trigger the subjunctive form for commands. These include nunca (never), jamás (never/ever), and tampoco (neither/not either).
Nunca hagas eso sin consultarme.(Never do that without consulting me.)Jamás me mientas.(Never lie to me.)Si no te gusta, tampoco lo comas.(If you don't like it, don't eat it either.)
yo forms or stem changes that affect these commands?This primarily requires systematic memorization and practice. When learning new verbs, always make note of their yo form in the present indicative. If this form exhibits any deviation from a simple -o ending (e.g., salgo, hago, conozco, pido) or a vowel change in the stem (cierro, vuelvo), that irregularity will carry directly into the present subjunctive and, consequently, into the negative tú command. Regular exposure and dedicated conjugation drills are the most effective strategies for internalizing these patterns.
tú commands the same in Spain and Latin America?Yes, the negative tú commands are grammatically identical across all Spanish-speaking regions. The tú subjunctive forms, which are the basis for these commands, are universally consistent. Any regional variations in informal commands primarily concern the vosotros form (used in Spain for informal plural "you"), which has distinct conjugations not used in Latin America (where ustedes serves for both formal and informal plural "you"). Therefore, when addressing a single person informally with tú, the commands remain consistent globally.
tú commands?Reflexive verbs follow the established pattern. The reflexive pronoun te (for tú) is always placed between the negative word (no) and the conjugated verb.
No te sientes ahí.(Don't sit there.) (sentarse)No te preocupes.(Don't worry.) (preocuparse)No te vayas.(Don't leave.) (irse)
While commands are direct by nature, you can mitigate their harshness by incorporating polite phrases or reframing them slightly.
- Add
por favor:No lo hagas, por favor.(Please, don't do it.) - Use
te pido que...(I ask you to...):Te pido que no salgas tan tarde.(I ask you not to leave so late.) This is an indirect command that still uses the subjunctive. - Employ conditional phrases like
sería mejor si no...(It would be better if you didn't...):Sería mejor si no gastaras tanto.(It would be better if you didn't spend so much.) This lessens directness.
