- Un estudiante escribe la siguiente oración para darle un consejo negativo a su amigo: 'No me lo digas nunca.' Su profesor señala que hay un error. ¿Cuál es el problema con esta oración?
Answer: La oración no contiene ningún error gramatical; el mandato negativo y la colocación de pronombres son correctos.
When working with negative commands in Spanish, two grammar rules are essential: verb mood and pronoun placement. For negative tú commands, you use the present subjunctive form of the verb, and object pronouns are placed before the conjugated verb — sandwiched between no and the verb itself.
The sentence "No me lo digas nunca" follows both rules perfectly. Digas is the correct present subjunctive form of decir for a negative tú command. The pronouns me and lo appear before digas, in the correct order (indirect before direct). And nunca simply reinforces the negation, which is grammatically valid in Spanish — unlike English, double negatives are standard and correct in Spanish. So B is right: there is no error in the sentence.
Now look at the distractors. A claims pronouns go after the verb in negative commands — this is actually the rule for affirmative commands (Dímelo), not negative ones. Mixing these two rules up is one of the most common Spanish mistakes, so watch for it. C suggests that nunca changes the mood of the sentence, requiring the indicative dices — this is false. Nunca is an adverb that modifies frequency; it doesn't alter the grammatical mood or make a command into a statement. D claims lo should follow the verb, forming No me digas lo — pronouns never get split like this or placed after the verb in a negative command.
Your study tip: always ask yourself — is this an affirmative or negative command? That single question determines everything about pronoun placement in Spanish.
- ¿Cuál de las siguientes oraciones contiene un mandato negativo de nosotros formado correctamente?
Answer: No hablemos tan rápido durante la presentación.
When a question asks about negative nosotros commands, you need to recall that Spanish uses the present subjunctive to form these commands — not the regular present indicative. The formula is simple: take the yo form of the present tense, drop the -o, and add the opposite vowel ending (-emos for -ar verbs, -amos for -er/-ir verbs). For negative commands, just place no in front.
For the verb hablar, the yo form is hablo → drop the -o → habl- → add -emos → hablemos. With the negative, you get No hablemos, which is exactly what answer A shows. This is the correctly formed negative nosotros command, making A the right choice.
Answer B, No hablamos, uses the regular present indicative ("we do not speak"), not the subjunctive. It sounds like a statement of fact, not a command — a very common trap since hablamos and the subjunctive hablemos look almost identical.
Answer C, No habléis, is actually a negative vosotros command, used in Spain for the "you all" group. The -*áis/-éis* ending signals vosotros, not nosotros — wrong subject entirely.
Answer D, No hablamos nosotros, adds the pronoun nosotros but still uses the indicative hablamos, so it has the same flaw as B. Adding the explicit pronoun doesn't fix the verb form.
A quick study tip: watch for the -emos/-amos subjunctive ending as your signal for nosotros commands. If you see -amos on an -ar verb (like hablamos), that's indicative — not a command.
- ¿Cuál de los siguientes mandatos negativos de tú contiene un error de formación?
Answer: No sabes la respuesta sin estudiar primero.
When forming negative tú commands in Spanish, you follow a specific rule: take the yo form of the present tense, drop the -o, and add the opposite vowel ending (-es for -ar verbs, -as for -er/-ir verbs). This is the subjunctive form, and it applies to all negative tú commands — including irregular verbs. The key question to ask yourself is: "Is this verb actually in command form, or is it something else entirely?"
Option C, No sabes la respuesta sin estudiar primero, is the incorrect formation. "Sabes" is simply the regular present indicative form of saber (tú sabes). To make a proper negative tú command, it should be No sepas la respuesta... — using the subjunctive stem sep- plus -as. As written, the sentence isn't a command at all; it's a statement of fact.
Options A, B, and D are all correctly formed negative tú commands. A uses vengas, the irregular subjunctive of venir (yo vengo → veng- + as). B uses pongas, from poner (yo pongo → pong- + as). D uses vayas, the irregular subjunctive of ir, which you simply have to memorize. All three follow proper command structure.
A helpful study tip: whenever you see a negative tú command, mentally check — does the verb end in -es (for -ar verbs) or -as (for -er/-ir verbs)? If it looks like a normal present-tense conjugation instead, that's your red flag that something is wrong.
- Elena quiere darle un mandato negativo informal a su hermano. ¿Cuál de las siguientes opciones expresa correctamente 'Don't talk with your mouth full'?
Answer: No hables con la boca llena.
When forming negative informal commands (mandatos negativos informales) in Spanish, you cannot simply put "no" in front of the regular present tense verb. Instead, you must use the present subjunctive form of the verb. For tú commands specifically, take the yo-form of the present tense, drop the -o, and add the opposite vowel ending: -ar verbs get -es, and -er/-ir verbs get -as.
For hablar: yo hablo → habl- → hables. So the correct negative informal command is "No hables con la boca llena" — which is answer B.
Here's why the other options miss the mark: A ("No hablas con la boca llena") uses the regular present tense indicative, which simply states a fact ("You don't talk with your mouth full") rather than issuing a command — a very common trap. C ("No hablas tú con la boca llena") makes the same indicative error and adds the subject pronoun tú, which doesn't fix the problem; adding a pronoun doesn't transform a statement into a command. D ("No hable con la boca llena") uses the usted subjunctive form, which is correct for a formal or polite command — but the question specifically asks for an informal command directed at a younger sibling, so this is the wrong register entirely.
Study tip: A quick way to remember this: negative tú commands = present subjunctive, always. If you see no + present indicative, it's a statement, not a command. Drilling the subjunctive conjugations for common verbs will save you on questions like this.
- Un estudiante quiere decirle a su amigo 'No te levantes temprano mañana' usando un mandato negativo informal con un verbo reflexivo. El estudiante escribe: 'No levántate temprano mañana.' ¿Qué error cometió el estudiante?
Answer: El pronombre reflexivo 'te' está unido al verbo, pero en los mandatos negativos debe colocarse antes del verbo, produciendo 'No te levantes temprano mañana.'
When working with negative informal commands (mandatos negativos informales) involving reflexive verbs, you need to keep two rules in mind simultaneously: how to form the negative command, and where to place the reflexive pronoun.
For negative tú commands, you form the verb using the yo-form present tense as your base, drop the -o, and add the opposite vowel ending (-es for -ar verbs, -as for -er/-ir verbs). For levantarse, that gives you levantes. The critical rule is that reflexive pronouns in negative commands must appear before the conjugated verb, not attached to it. So the correct sentence is No te levantes temprano mañana — pronoun first, then verb.
The student's sentence No levántate breaks this rule by attaching te to the verb with an accent, which is actually how you'd structure a positive command (Levántate). That's the error, confirming that B is correct.
As for the distractors: A claims the verb should come from levantas (the tú present indicative), which is wrong — negative commands derive from the yo-form, not the tú conjugation. C invents a rule about -iendo endings, which belong to the present participle/gerund, never to imperative commands. D suggests dropping te entirely, but reflexive pronouns are always required with reflexive verbs — omitting te here would change the meaning entirely.
Study tip: Think of it this way — in Spanish, pronoun placement flips depending on command type: attached at the end for positive commands, placed before the verb for negative ones. This flip is one of the most frequently tested patterns in Spanish 2.
- Marta decide usar un mandato negativo informal con dos pronombres de objeto. ¿Cuál de las siguientes opciones es la correcta?
Answer: No se los cuentes a nadie.
When forming a negative informal command with two object pronouns in Spanish, you need to remember two key rules: (1) both pronouns come before the conjugated verb in negative commands, and (2) when an indirect object pronoun (le/les) appears before a direct object pronoun starting with l- (lo, la, los, las), the indirect pronoun always changes to se.
In this sentence, Marta wants to say "Don't tell them (her secrets) to anyone." The verb is contar, the direct object pronoun is los (los secretos), and the indirect object pronoun is le → which becomes se before los. In a negative tú command, both pronouns precede the verb, giving you: No se los cuentes a nadie. That's why C is correct — the pronoun order is se + los, placed before the negated subjunctive form cuentes.
Looking at the wrong answers: A (No cuéntaselos) attaches the pronouns to the verb as if it were an affirmative command — but negative commands never attach pronouns to the end of the verb. B (No los se cuentes) has two problems: the pronouns are in the wrong order (it should be se los, not los se), and se never follows a direct object pronoun. D (No cuentes los se) places the pronouns after the verb and in the wrong order entirely, which is grammatically impossible in any command form.
A helpful rule to memorize: in Spanish, pronoun order always follows RID — Reflexive → Indirect → Direct. And in negative commands, those pronouns always stay in front of the verb.
- Un estudiante de español quiere escribir el mandato negativo de usted para el verbo 'ser.' ¿Cuál de las siguientes formas es la correcta, y por qué razón es fácil cometer un error con este verbo en particular?
Answer: 'No sea' — porque 'ser' tiene un subjuntivo completamente irregular (sea, seas, sea…) que no se puede derivar de la primera persona del presente indicativo, y 'sea' es la forma de subjuntivo correspondiente a usted.
When forming negative usted commands in Spanish, you always use the present subjunctive form corresponding to usted (third person singular). The tricky part is knowing how to build that subjunctive form — and this is exactly where ser trips students up.
For most verbs, you derive the present subjunctive by taking the yo form of the present indicative, dropping the -o, and adding the opposite vowel endings. For example, hablar → hablo → habl- → hable. But ser completely breaks this rule. Its yo form is soy, yet the subjunctive is NOT soy → soy- → soya. Instead, ser has a fully irregular subjunctive paradigm: sea, seas, sea, seamos, seáis, sean. This form must simply be memorized because it cannot be predicted from the indicative. Therefore, the correct negative usted command is "No sea" — making D the right answer.
Here's why the other options fail: A is wrong because no es is simply the present indicative, not a subjunctive form at all — indicative is never used for negative formal commands. B is wrong because seas is the tú subjunctive form, not usted; confusing subject pronouns here is a classic error. C is wrong because sé is actually the affirmative tú command for ser, and the rule it describes — using the yo indicative form — does not apply to *ser*'s subjunctive anyway.
As a study tip: memorize the irregular subjunctive verbs using the acronym DISHES (Dar, Ir, Saber, Haber, Estar, Ser) — these six verbs have unpredictable subjunctive forms that appear constantly on exams.
- Un estudiante quiere decirle a su amiga: 'Don't tell it to me now' usando un mandato negativo informal con dos pronombres de objeto. El estudiante escribe: 'No me lo dices ahora.' ¿Qué DOS errores contiene esta oración?
Answer: El verbo está en indicativo en lugar de subjuntivo (debe ser 'digas'), mientras que el orden y la posición de los pronombres antes del verbo ya son correctos, produciendo: 'No me lo digas ahora.'
When forming negative informal commands in Spanish, two things must be true: (1) the verb must be in the present subjunctive, and (2) object pronouns must be placed before the conjugated verb. The student's sentence "No me lo dices ahora" tests both of these rules at once.
The verb dices is the present indicative form — what you use for statements like "you tell." For negative tú commands, you need the subjunctive: digas. That's the first error. Now look at the pronouns: me lo appears before the verb, which is exactly where pronouns belong in negative commands. The indirect object pronoun (me) also correctly comes before the direct object pronoun (lo), following the standard IO → DO order. So the pronoun placement and order are actually correct — the only fix needed is the verb. The corrected sentence is "No me lo digas ahora." That makes D the right answer.
Option A wrongly claims me should follow the verb and also misorders the pronouns, inventing a rule that doesn't exist for negative commands. Option B incorrectly says the pronoun order should be lo me — Spanish always places the indirect object pronoun before the direct object pronoun, so me lo is right. Option C claims pronouns must go after the verb in negative commands, which is the rule for affirmative commands only — a classic mix-up.
Study tip: Remember the affirmative/negative split: affirmative tú commands attach pronouns after the verb (dímelo), while negative commands keep pronouns before the subjunctive verb (no me lo digas). Don't swap these rules!
- Luis intenta darle un mandato negativo informal a Carlos, pero comete un error. ¿Cuál sería la forma correcta del mandato, y qué tipo de error cometió Luis?
Answer: 'No abras la ventana' — Luis usó la forma del presente indicativo de tú ('abre') en lugar del presente de subjuntivo requerido para mandatos negativos de tú.
When forming negative informal (tú) commands in Spanish, you cannot simply use the affirmative tú command form — the grammar works differently depending on whether the command is positive or negative. Affirmative tú commands use the third-person singular present indicative ("abre"), but negative tú commands require the present subjunctive of tú ("abras"). This is a crucial distinction and a very common source of errors.
Luis says "No abre la ventana," which is the affirmative tú command form (or the third-person singular indicative), not the correct negative command. The correct form is "No abras la ventana," using the present subjunctive. To form it: start from the yo form of the present indicative ("abro"), drop the -o, and add the opposite vowel ending for -ar verbs (-es → "abras"). Answer A correctly identifies both the error and the solution.
Answer B is wrong because "No abres" is simply the present indicative tú conjugation — that's a statement of fact ("You don't open the window"), not a command at all. Answer C is wrong because "No abriste" is the preterite tense, referring to a completed past action — using past tense as a command makes no grammatical sense in this context. Answer D is wrong because while "abra" IS the present subjunctive, it belongs to the usted command form, not tú. The tú subjunctive form requires the -es ending: "abras," not "abra."
A handy study tip: memorize the phrase "negative tú = present subjunctive tú." Any time you see a negative tú command question, immediately ask yourself: "Did they use the subjunctive form with the opposite vowel ending?" That check alone will save you from the most common mistake on this topic.
