Mastering Spanish Grammar: Conjunctions, Negation, Questions, and Commands

Welcome to your complete revision guide for one of the most vital grammar chapters in AQA A-Level Spanish (7692)! Whether you are aiming for an \(A^*\) or trying to turn tricky sentence structures into easy marks, mastering these four building blocks will instantly level up your writing (Paper 2), your listening and translation accuracy (Paper 1), and your spontaneous discussion (Paper 3).

Don't worry if these rules seem detailed at first. We will break down every single concept step by step, look at common pitfalls, and explore simple tricks to remember them effortlessly.

1. Conjunctions (Las Conjunciones)

Conjunctions are the linking words that join sentences, phrases, or ideas together. They are essential for turning short, robotic sentences into fluid, sophisticated Spanish.

A. Coordinating Conjunctions

These link clauses or words that carry equal grammatical weight:

  • Copulative (Adding):
    • y (and) \(\implies\) Changes to e before words starting with an i- or hi- sound to avoid awkward pronunciation (e.g., padre e hijo).
      Exception: It remains y before diphthongs starting with hie- (e.g., cobre y hierro).
    • ni... ni... (neither... nor).
  • Disjunctive (Choice):
    • o (or) \(\implies\) Changes to u before words starting with o- or ho- (e.g., siete u ocho).
  • Adversative (Contrasting):
    • pero (but / however).
    • sino (but rather / instead).

The Golden Rule: Pero vs. Sino vs. Sino que

This is one of the most common mistakes flagged by AQA examiners! Here is how to keep them straight:

  • Use pero when adding a qualification or contrasting thought (the first clause can be positive or negative):
    Estudia mucho, pero no saca buenas notas. (He studies a lot, but he doesn't get good grades.)
  • Use sino when the first clause is negative and you are replacing it with a direct alternative (noun, adjective, or prepositional phrase):
    No es español sino mexicano. (He is not Spanish, but rather Mexican.)
  • Use sino que when replacing a negative clause with a new conjugated verb clause:
    No estudia sino que trabaja. (He doesn't study, but rather he works.)

B. Subordinating Conjunctions and Mood Selection

When you use subordinating conjunctions, you must decide between the Indicative (facts, certainty, habits) and the Subjunctive (wishes, unfulfilled events, possibilities).

1. Always Indicative (Cause / Reason)

Because reasons state facts, these conjunctions take the Indicative:

  • porque (because)
  • ya que / puesto que / dado que (given that / since)
  • como (as / since) \(\implies\) Must stand at the very start of the sentence (e.g., Como no tenía dinero, no fue al cine).
2. Always Subjunctive (Purpose, Condition, Exception)

These conjunctions trigger the Subjunctive 100% of the time:

  • Purpose: para que (so that), a fin de que (in order that).
    Note: If there is no change of subject, do not use the subjunctive; use para + Infinitive (e.g., Estudio para aprobar).
  • Proviso / Condition: con tal de que (provided that), a condición de que (on condition that), siempre que / siempre y cuando (provided that).
  • Supposition / Exception: a no ser que (unless), a menos que (unless), sin que (without).
  • Fixed Temporal: antes de que (before) \(\implies\) Always requires the Subjunctive, even when describing past events!
3. Time Conjunctions (Conjunctions of Time)

Includes: cuando (when), en cuanto / tan pronto como (as soon as), mientras (while), hasta que (until), después de que (after).

  • Use Indicative: For habitual actions in the present or completed actions in the past.
    Cuando llego a casa, ceno. (Habitual present \(\implies\) Indicative)
    Cuando llegó el tren, subimos. (Past event \(\implies\) Indicative)
  • Use Subjunctive: When referring to a future, unfulfilled, or anticipated action.
    Cuando llegue a casa, cenaré. (Future intention \(\implies\) Subjunctive)
4. Concession: Aunque and A pesar de que
  • Indicative: For a known fact or reality.
    Aunque llueve, salgo. (Although it is raining [and I know it is], I am going out.)
  • Subjunctive: For a hypothetical situation, uncertainty, or an obstacle that doesn't change the outcome ("even if").
    Aunque llueva mañana, saldré. (Even if it rains tomorrow, I will go out.)
Receptive Use of Que (AQA Specification Item)

In spoken or informal written Spanish, que can introduce an independent explanatory or exclamatory warning clause:
¡Cuidado, que se va a quemar la tortilla! (Watch out, [for] the omelette is going to burn!)

Key Takeaway: Time clauses referring to the future and all purpose/condition clauses require the Subjunctive. Direct replacements after a negative statement require sino or sino que, not pero.

2. Negation (La Negación)

Spanish handles negative sentences differently from English. While "double negatives" are incorrect in English, in Spanish they are often strictly required.

Core Negative Words

  • no (no / not)
  • nada (nothing / not anything)
  • nadie (nobody / no one)
  • nunca / jamás (never)
  • ninguno/a (none / not any) \(\implies\) Drops the -o to become ningún before a masculine singular noun (e.g., ningún problema).
  • tampoco (neither / not either)
  • ni... ni... (neither... nor)
  • ya no (no longer)
  • ni siquiera (not even)

The Rules of Word Order

  1. Post-Verbal Rule (Double Negation): If the negative word is placed after the conjugated verb, you must place no (or another negative word) directly before the verb:
    • No tengo nada. (I have nothing / I don't have anything.)
    • No vino nadie. (Nobody came.)
    • No come carne nunca. (He never eats meat.)
  2. Pre-Verbal Rule: If the negative word comes before the verb, no is omitted:
    • Nada tengo.
    • Nadie vino.
    • Nunca come carne.
  3. Multiple Negation: You can stack several negative words in a single sentence without them canceling each other out:
    • No le dije nada a nadie nunca. (I never said anything to anyone.)

Examiner Warning: Never combine pre-verbal negatives with no. Writing No nadie vino is incorrect. Choose either Nadie vino or No vino nadie.

Key Takeaway: Before the verb = single negative (Nadie sabe). After the verb = double negative required (No sabe nadie).

3. Questions (Las Interrogaciones)

Punctuation and Syntax

  • Punctuation: Spanish questions always open with an inverted question mark (¿) at the start of the question clause and close with (?).
  • Word Order (Inversion): The verb almost always comes before the subject:
    ¿Cuándo llegará el tren? (When will the train arrive?)
  • Focalisation: You can emphasize a subject by placing it before the question marker:
    Tú, ¿qué opinas? (You, what do you think?)

Interrogative Words (All Have Written Accents!)

Every Spanish question word carries a written tilde (accent mark), even in indirect questions:

  • ¿Qué? (What? / Which?): Asks for a definition or precedes a noun (e.g., ¿Qué libro lees?).
  • ¿Quién? / ¿Quiénes? (Who? / Whom?): Must match singular or plural subjects (e.g., ¿Quiénes son ellos?).
  • ¿Cuál? / ¿Cuáles? (Which / Which one?): Used when choosing from a set.
    Rule: ¿Cuál? is never followed directly by a noun in standard Spanish.
    Say: ¿Qué falda prefieres? or ¿Cuál de las faldas prefieres? (NOT ¿Cuál falda prefieres?).
  • ¿Cuánto/a/os/as? (How much? / How many?): Agrees in gender and number with the noun.
  • ¿Cómo? (How?)
  • ¿Dónde? / ¿Adónde? (Where? / Where to?)
  • ¿Cuándo? (When?)
  • ¿Por qué? (Why? — written as two words with an accent).

Watch Out: The Four Forms of "Por que"

  • ¿Por qué? = Why? (Question / Interrogative)
  • Porque = Because (Conjunction)
  • El porqué = The reason / The cause (Noun, takes an accent and article)
  • Por que = For which / That (Preposition + relative)

Indirect Questions

When questions are embedded inside statements, they keep their written accents:

  • No sé dónde está la biblioteca. (I don't know where the library is.)
  • Quiero saber qué pasó. (I want to know what happened.)

Key Takeaway: Always include the opening ¿, invert subject and verb, and make sure every question word has its accent mark!

4. Commands and Imperatives (Los Mandatos)

Commands are used to give orders, instructions, and advice. Spanish uses distinct forms depending on whether you are talking to someone casually (tú, vosotros), formally (usted, ustedes), or making a group suggestion (nosotros).

A. Overview of Command Forms

1. Affirmative Tú (Informal Singular)

Take the 3rd person singular of the Present Indicative:

  • Hablar \(\implies\) ¡Habla!
  • Comer \(\implies\) ¡Come!
  • Vivir \(\implies\) ¡Vive!

The 8 Irregular Affirmative Tú Commands:

  • Decir \(\implies\) di
  • Hacer \(\implies\) haz
  • Ir \(\implies\) ve
  • Poner \(\implies\) pon
  • Salir \(\implies\) sal
  • Ser \(\implies\) sé
  • Tener \(\implies\) ten
  • Venir \(\implies\) ven
2. Negative Tú

Use no + Present Subjunctive (tú form):

  • No hablar \(\implies\) ¡No hables!
  • No comer \(\implies\) ¡No comas!
  • No vivir \(\implies\) ¡No vivas!
3. Formal Commands (Usted / Ustedes)

Always use the Present Subjunctive (3rd person singular or plural) for both affirmative and negative commands:

  • Usted: ¡Hable! / ¡No hable! — ¡Coma! / ¡No coma!
  • Ustedes: ¡Hablen! / ¡No hablen! — ¡Coman! / ¡No coman!
4. Plural Informal (Vosotros/as)
  • Affirmative: Drop the final -r of the infinitive and replace it with -d:
    • Hablar \(\implies\) ¡Hablad!
    • Comer \(\implies\) ¡Comed!
    • Vivir \(\implies\) ¡Vivid!
    Reflexive rule: Drop the -d before adding -os (e.g., ¡Sentaos!). Exception: irse \(\implies\) ¡Idos!
  • Negative: Use no + Present Subjunctive (vosotros form):
    • ¡No habléis! / ¡No comáis! / ¡No viváis!
5. First Person Plural (Nosotros/as — "Let's...")
  • Use the Present Subjunctive (nosotros form):
    • ¡Hablemos! (Let's speak!) / ¡Comamos! (Let's eat!)
  • Reflexive rule: Drop the final -s before adding -nos (e.g., ¡Sentémonos!, ¡Vámonos!).

B. Pronoun Placement with Commands (Crucial Exam Skill!)

Where direct, indirect, or reflexive pronouns go depends entirely on whether the command is affirmative or negative:

  1. Affirmative Commands (Attach to the end): Pronouns must join to the back of the verb as a single word (enclitic).
    Accent Alert: If attaching pronouns pushes the stress back beyond the penultimate syllable, you must add an accent mark to preserve the original stress:
    • ¡Hazlo! (Do it! — 2 syllables, no accent needed)
    • ¡Dímelo! (Tell it to me! — accent required on the root vowel)
    • ¡Cómpratelo! (Buy it for yourself! — accent required)
  2. Negative Commands (Place before the verb): Pronouns must go before the verb as separate words:
    • ¡No lo hagas! (Don't do it!)
    • ¡No me lo digas! (Don't tell it to me!)
    • ¡No te lo compres! (Don't buy it for yourself!)

Key Takeaway: Affirmative = pronouns glued to the end (add accents if needed). Negative = pronouns in front of the verb.

Quick Reference Summary

  • Pero vs. Sino: Use pero for "but"; use sino for "but rather" after a negative statement (or sino que if followed by a finite verb).
  • Conjunctions + Subjunctive: Always after para que, a menos que, antes de que; after cuando / en cuanto only when referring to the future.
  • Negation: Post-verbal negative requires a pre-verbal no (No veo a nadie). Pre-verbal negative stands alone (Nadie viene).
  • Questions: Always use opening ¿ and closing ?, invert subject/verb, and place accents on question words (¿Qué?, ¿Dónde?).
  • Commands: Affirmative tú = 3rd person indicative (watch the 8 irregulars!). All negative commands = Subjunctive. Attach pronouns to affirmative commands; place them before negative commands.
