Introduction
Learning Spanish verb commands can be challenging for English speakers, especially when dealing with negative imperatives. One of the most common and practical negative commands you will encounter is no digas, which means do not say or do not tell in English. This phrase is fundamental in Spanish communication, whether you are warning someone not to reveal a secret, asking them not to speak negatively, or simply instructing them not to say something inappropriate. Understanding how to properly use no digas and similar negative imperative forms will significantly improve your ability to communicate naturally with Spanish speakers and help you express commands and warnings with confidence and clarity.
Understanding the Negative Imperative Form
What is a Negative Imperative?
A negative imperative is a grammatical structure used to command or instruct someone not to do something. In Spanish, negative imperatives are formed differently from positive commands, and they follow specific conjugation patterns depending on the subject pronoun and the verb type. The negative imperative is essential for communicating prohibitions, warnings, and restrictions in everyday Spanish conversation.
Unlike positive commands in Spanish, which vary significantly between regular and irregular verbs, negative imperatives maintain a more consistent structure. They are formed using the present subjunctive mood combined with the word no, which indicates negation. This structure applies to all verb types: regular verbs ending in ar, er, and ir, as well as irregular verbs.
The Structure of Negative Imperatives
The basic structure for forming a negative imperative is simple: place the word no before the present subjunctive form of the verb. For the second person singular informal command (tú form), you are essentially saying not to do something to someone you know casually or someone of your same age group.
For example, with regular verbs:
Regular ar verb (hablar – to speak): no hables
Regular er verb (comer – to eat): no comas
Regular ir verb (vivir – to live): no vivas
Conjugating the Verb Decir (To Say)
Why Decir is Irregular
The verb decir is one of the most commonly used irregular verbs in Spanish. It means to say, to tell, or to speak, and it appears frequently in conversations about communication and information sharing. Because decir is irregular, it does not follow the standard conjugation patterns of regular verbs, which makes learning its forms particularly important for Spanish learners.
The present subjunctive form of decir is based on the irregular stem dig, not the regular infinitive stem dic. This stem appears in various conjugations throughout different tenses and moods. For the tú (informal you) form in the present subjunctive, the conjugation is digas.
The Formation of No Digas
To form the negative tú command no digas, we combine the negation word no with the second person singular present subjunctive form of decir. The result is no digas, which literally translates to you do not say or do not say in the informal imperative sense.
Breaking down the formation:
Negation particle: no
Present subjunctive of decir (tú form): digas
Complete negative imperative: no digas
This construction follows the standard pattern for all negative imperative forms in Spanish, making no digas an excellent example of how the grammar system works consistently across different verbs and situations.
When and How to Use No Digas
Common Situations for Using No Digas
The phrase no digas appears in numerous everyday situations in Spanish-speaking countries. You would use this command when you want to instruct someone not to say something, whether to protect information, maintain politeness, or prevent misunderstandings. Some common scenarios include warning someone not to reveal a secret, asking them not to be rude or offensive, telling them not to mention a sensitive topic, or instructing them not to spread rumors or gossip.
For instance, if your friend wants to tell your boss about a mistake you made, you might say no digas nada (don’t say anything) to ask them to keep quiet. If someone is about to make an inappropriate comment at a family gathering, you could use no digas eso (don’t say that) to prevent them from speaking.
Formal vs. Informal Use
It is crucial to understand that no digas is the informal singular form used with people you know well, such as friends, family members, or peers. This form uses the tú pronoun and is appropriate in casual, friendly contexts. If you need to give the same command to someone you address formally or respectfully, you would use a different form.
For formal situations with people you do not know well or those who deserve formal respect, such as teachers, bosses, or strangers, you would use no diga instead, which is the formal usted form. Similarly, if you are addressing multiple people informally, you would use no digáis in Spain or no digan in Latin American Spanish, depending on the region and context.
Related Negative Imperative Forms of Decir
The Formal Command: No Diga
The no diga form is the formal singular negative imperative, used when addressing someone with the usted pronoun. This is the respectful form you would use in professional environments, with strangers, authority figures, or anyone deserving of formal treatment. The subjunctive stem remains the same (dig), but the ending changes to reflect the formal register.
Example: Doctor, no diga a nadie sobre mi condición.
Translation: Doctor, do not tell anyone about my condition.
The Plural Commands: No Digáis and No Digan
When addressing multiple people informally in Spain, you use the vosotros form, which is no digáis. This form is rarely used outside of Spain but is important to recognize if you plan to spend time there. The ending is distinct, with the characteristic vosotros marker áis.
In Latin America and much of the Spanish-speaking world, the plural informal form is replaced by the formal plural usted form, which is no digan. This form addresses multiple people with the same respect level as the singular no diga, creating a consistent formal register throughout the sentence.
Examples:
Spain (informal plural): Chicos, no digáis nada sobre la sorpresa.
Latin America (plural): Amigos, no digan nada sobre la sorpresa.
Translation: Guys, do not say anything about the surprise.
Practical Examples and Usage Scenarios
Protecting Secrets and Privacy
One of the most common reasons to use no digas is to ask someone to keep information confidential. In these situations, the phrase often appears with additional context about what should not be said.
Example: No digas que vi a tu ex en la tienda.
Translation: Do not say that you saw your ex at the store.
Another example: No digas mi número de teléfono a extraños.
Translation: Do not give my phone number to strangers.
These examples show how no digas is used practically to protect privacy and maintain confidentiality in relationships and social settings.
Preventing Offensive Speech
You might also use no digas to prevent someone from making rude, offensive, or hurtful comments. This usage reflects the importance of politeness and respect in Spanish-speaking cultures.
Example: No digas cosas tan crueles sobre su apariencia.
Translation: Do not say such cruel things about his appearance.
Another example: No digas palabras groseras en la mesa.
Translation: Do not use vulgar language at the table.
Avoiding Uncomfortable Topics
In family or social gatherings, no digas is useful for steering conversations away from uncomfortable or sensitive subjects that might cause conflict or embarrassment.
Example: No digas nada sobre política en la cena.
Translation: Do not say anything about politics at dinner.
Another example: No digas sus problemas a todos.
Translation: Do not tell everyone about his problems.
Common Phrases and Expressions with No Digas
Several fixed expressions and common phrases incorporate no digas in everyday Spanish conversation. Learning these phrases will help you communicate more naturally and effectively.
The phrase no digas nada means do not say anything and is probably the most frequently used form. It is a complete command on its own, often used when someone is about to speak inappropriately or when you want them to remain silent about a matter.

Important Notes on Pronunciation and Accent Marks
The correct pronunciation of no digas is essential for effective communication. The word no is pronounced with a short oh sound, and digas is pronounced with a stressed first syllable: DEE-gas. The stress falls on the first syllable of the word digas, which is important for distinguishing it from other verb forms.
In written Spanish, the word no digas does not carry an accent mark on either word. The subjunctive form digas does not require an accent because the stress naturally falls on the first syllable according to Spanish pronunciation rules.
