The 10 Grammar Structures That Keep Appearing in DELE B2's Uso de la Lengua (And How to Stop Getting Them Wrong)

Most B2 candidates study grammar. Almost none study the right grammar.

You've done your verb tables. You know the preterite from the imperfect. You've read about the subjunctive until your eyes blurred. And then you sit down with a past Uso de la Lengua paper and you still lose points — not on the 'hard' stuff, but on these small, irritating structures you've seen a hundred times and somehow keep getting wrong.

That's because DELE B2's Uso de la Lengua doesn't test grammar randomly. It tests a recurring shortlist of structures — the ones that genuinely separate B2 speakers from B1 ones. Once you know what's actually on that list, preparation gets a lot more efficient. Here it is.

What does Uso de la Lengua actually test?

Uso de la Lengua is the grammar and vocabulary section of the DELE B2 reading exam. It contains three tareas: a multiple-choice cloze (Tarea 4), a word-formation or gap-fill task (Tarea 5), and a sentence transformation task (Tarea 6). Together they are worth a significant chunk of your reading score — and Tarea 6, the transformations, is where most educated guesses go to die.

The structures below appear across all three tareas, but especially in Tareas 5 and 6. They're not obscure edge-cases. They're the bread-and-butter of written B2 Spanish — the kind of thing a native would use without thinking, but that trips up learners who learned grammar in neat compartments instead of in context.

Structure 1: Subjunctive vs Indicative After Verbs of Communication and Reporting

You know 'quiero que vengas' takes a subjunctive. Fine. But what about 'dice que venga' vs 'dice que viene'? This is where real B2 grammar lives. When a reporting verb like decir, pedir, recomendar, or insistir en conveys a command or wish, the subordinate clause uses subjunctive. When it just reports a fact, it uses indicative. The exam will build a sentence specifically designed to make you choose wrong.

Fix: Map the verb to a meaning. Decir (affirm) → indicative. Decir (instruct) → subjunctive. Write five example pairs in your notebook and you'll never confuse them again.

• Me dice que llega tarde → (he's telling me a fact)
• Me dice que llegue puntual → (he's telling me what to do)
• Recomienda que prueben la paella → (recommendation = subjunctive, always)

Structure 2: Ser vs Estar With Adjectives That Change Meaning

This is a trap the exam sets precisely because you think you've already mastered it. The classic pairs — listo (clever vs ready), malo (bad vs ill), aburrido (boring vs bored) — appear regularly, but Tarea 4 and 5 also test less-memorized ones: vivo (clever vs alive), seguro (safe as a quality vs certain in this moment), rico (tasty vs wealthy).

The fix isn't to memorize a bigger list. It's to internalize the underlying logic: ser describes inherent or categorizing qualities; estar describes states, results of change, or the speaker's perception right now. When you see an adjective, ask yourself: 'Is this a category this person belongs to, or a state they're currently in?'

Structure 3: Conditional Perfect and Pluperfect Subjunctive in Hypotheticals

If you've ever written 'Si habría sabido...' on an exam, this one's for you. The third conditional in Spanish — past situations that didn't happen — demands a very specific pairing: Si + pluperfect subjunctive (hubiera/hubiese + participio) in the if-clause, and conditional perfect (habría + participio) in the result clause. The exam will give you one half of the sentence and ask you to complete the other. It will also test whether you can swap 'hubiera' for 'de haber + infinitivo' in formal registers.

Sentence transformations love this structure because there's almost no way to guess it — you either know the pattern cold or you don't.

• Si lo hubiera sabido, te habría llamado.
• De haberlo sabido, te habría llamado. (formal equivalent — same meaning)
• Common error: Si habría sabido → this is wrong in any Spanish exam, always

Structure 4: Passive Constructions — Ser + Participio vs Se Pasiva

Spanish has two main passive structures and the exam tests both, plus the passive of result (estar + participio). The distinction matters: 'El edificio fue construido en 1920' focuses on the action; 'El edificio está construido sobre roca' describes the resulting state. Then there's 'Se construyó el edificio' — the impersonal passive that avoids naming an agent entirely.

Tarea 6 transformations often ask you to rewrite an active sentence as a passive one or flip between se-pasiva and ser-passive. Get comfortable producing all three forms, not just recognizing them.

Which grammar structures appear most in DELE B2 Tarea 6 transformations?

Tarea 6 — the sentence transformation task — most consistently tests: conditional/hypothetical clauses (structure 3 above), passive reformulations (structure 4), indirect speech transformations (shifting tense and pronouns when reporting what someone said), gerund vs infinitive alternation, and connectors that express contrast or concession (aunque + indicative vs subjunctive, a pesar de que, sin embargo, no obstante). These five areas account for the vast majority of transformation prompts across published past papers.

The reason they appear so often is structural: each of these requires you to make two or three simultaneous choices correctly — it's a reliable way to discriminate B2 from B1 without making the task impossibly obscure.

Structure 5: Aunque — The One Connector With a Secret

Most learners translate 'aunque' as 'although' and move on. But 'aunque' is one of the most nuanced connectors in Spanish because it changes meaning depending on the mood that follows it. 'Aunque está cansado, sigue trabajando' — indicative, meaning the speaker accepts this is a real fact. 'Aunque esté cansado, seguirá trabajando' — subjunctive, meaning even if (hypothetically) he's tired. One word, two completely different implications, and the exam will absolutely make you choose.

The practical rule: if you're presenting something as established fact, use indicative. If you're positing a hypothetical or conceding a possibility, use subjunctive. Tarea 4 will bury this choice inside a paragraph and you'll have maybe 40 seconds to make the call.

Structure 6: Indirect Speech Tense Backshift

Reporting what someone said requires you to backshift tenses correctly — and chain the pronoun and time-reference changes simultaneously. Present becomes imperfect. Future becomes conditional. Perfect becomes pluperfect. The exam will hand you a piece of direct speech — 'Tengo tiempo mañana' — and ask you to complete 'Dijo que...' If you write 'Dijo que tiene tiempo mañana' instead of 'tenía tiempo al día siguiente,' you've lost the point.

This structure combines tense knowledge with logic and attention to detail. Practice it by taking any piece of direct dialogue and transforming it systematically — it's one of the highest-return grammar drills you can do in the month before your exam.

• 'Voy a llamarte' → Dijo que iba a llamarme
• 'Lo he terminado' → Dijo que lo había terminado
• 'Vendré mañana' → Dijo que vendría al día siguiente

Structure 7: Gerund vs Infinitive — When Each One Is Required

Both are non-finite verb forms but they are not interchangeable, and the exam knows you default to one or the other when unsure. Infinitive follows prepositions ('antes de salir', 'para entender'), modal-equivalent verbs (deber, poder, soler), and verbs of will or preference (querer, preferir). Gerund is used for progressive aspect, manner ('salió corriendo'), and after certain verbs like seguir, llevar + time, and quedarse.

The sneaky one: 'Al + infinitivo' for simultaneous actions ('Al llegar, me llamó') — this looks like it should be a gerund but it's always infinitivo. Past papers have tested this exact substitution.

Structure 8: Por vs Para in Fixed and Nuanced Uses

You know the basics. Por = cause/duration/exchange. Para = purpose/destination/deadline. What the exam tests is the grey area: 'Habla muy bien para ser principiante' (contrast/concession with para), 'Lo tomaron por tonto' (mistaken identity, always por), 'Están por salir' (imminence, por), and 'Por mucho que estudies' (concessive, por). These less-discussed uses are exactly what Tarea 4's multiple-choice cloze drops in front of you when you're tired.

• Por tonto — taken for (identity/mistake)
• Para ser tan joven — considering (concession)
• Están por llegar — about to (imminence)
• Por más que insistas — however much (concessive)

Structure 9: Subjunctive in Relative Clauses With Indefinite or Negative Antecedents

This one quietly confuses even advanced learners. When the noun your relative clause refers to is hypothetical, non-existent, or unknown, the verb in the relative clause takes subjunctive. 'Busco un apartamento que tenga terraza' — I don't have it yet, it's hypothetical. 'Busco el apartamento que tiene terraza' — I know which one, it exists, indicative. In negative contexts: 'No hay nadie que sepa la respuesta' — no one existing, subjunctive.

Tarea 5 word-formation tasks sometimes require you to supply the correct verb form in exactly this context. If you don't recognize the trigger, you'll default to indicative and lose the point.

Structure 10: Connectors of Concession, Cause, and Consequence

The exam tests whether you can distinguish between connectors that look similar but behave differently grammatically. Puesto que and ya que take indicative (they present real causes). Para que always takes subjunctive (purpose). A fin de que is the formal equivalent. Sin embargo and no obstante are interchangeable but only work between clauses, not within them — unlike aunque. Así que and por lo tanto signal consequence but differ in register.

Tarea 4 loves to offer two plausible-sounding connectors and let the grammar decide. The right approach is to learn each connector's mood requirement and register level — not just its meaning.

• Puesto que / Ya que → indicative (cause, accepted fact)
• Para que / A fin de que → subjunctive (purpose, always)
• Aunque → indicative (real) or subjunctive (hypothetical)
• Sin embargo / No obstante → formal contrast, between clauses only
• Así que / Por lo tanto → consequence; así que is more colloquial

How should you actually practice these structures before the exam?

Flashcards won't cut it here. These structures are about making fast, correct choices under pressure — which means you need production practice, not just recognition. For each structure on this list, write five original sentences, then try to transform them using the paired form (active → passive, direct → indirect speech, real conditional → hypothetical). Time yourself. Make it uncomfortable.

Then use past DELE B2 papers — the INSTITUTO CERVANTES publishes official sample papers — and do Uso de la Lengua under timed conditions. After each attempt, don't just check the answers. Ask: 'Which structure did I misread the trigger for?' That diagnostic habit is worth more than two extra hours of random grammar exercises.

If you're not yet certain of your actual CEFR level — whether you're solidly B2 or still hovering at B1+ — Nivelo's free 5-minute CEFR test gives you an honest benchmark before you invest weeks in exam-specific prep. It won't flatter you, which is exactly the point.

The honest bottom line

None of these ten structures is unknowable. None requires years more study. What they require is precision — the kind that comes from understanding why a rule exists, not just what it is. The DELE B2 Uso de la Lengua is essentially a test of whether you've moved past mechanical grammar into intuitive control. These ten structures are the clearest markers of that transition.

Work through them deliberately, one at a time, with real sentences and transformation practice. By the time you sit the exam, the goal is that your brain produces the correct form before you've consciously reasoned through it. That's what B2 grammar actually feels like — and it's within reach.
