DELE B2 Subjunctive in Noun Clauses Spanish: Practice Test & Review
Noun clauses (also called substantive clauses) are the most common environment for the subjunctive in Spanish. They appear after verbs of will, emotion, doubt, and speech, and they are the backbone of B2 sentence structure. Knowing when the subjunctive is required — and when it is not — is the single most tested subjunctive skill at B2.
This page gives you a five-part practice quiz: an evaluation set to see where you stand, three practice sets to drill the trigger types, and a challenge set to confirm mastery. The grammar review below covers the four trigger categories, the two-subject rule, and the cases where the infinitive replaces the clause.
Noun clauses appear in every B2 reading passage that involves opinion, emotion, or reported speech. Master the trigger system and you can handle any subjunctive sentence the exam throws at you. Ready? Start with the evaluation set below.

The Rule
A noun clause (also called a substantive clause) functions as the object of a main verb. In Spanish, the subjunctive is required in the noun clause when the main verb expresses will, emotion, doubt, denial, or an impersonal evaluation — and when the two clauses have different subjects. When both clauses share the same subject, the infinitive replaces the clause.
The Four Trigger Categories
The subjunctive in noun clauses is triggered by four types of main verbs.
| Category | Examples | Subjunctive required? |
|---|---|---|
| Will and influence | querer, pedir, preferir, recomendar, insistir, prohibir, permitir, aconsejar | Yes |
| Emotion and evaluation | alegrar, sentir, sorprender, molestar, gustar, extrañar, es triste, es una pena | Yes |
| Doubt and denial | dudar, no creer, negar, no es verdad, no es cierto, es posible | Yes |
| Speech and thought | decir, pensar, creer (affirmative) | No — these take the indicative |
The first three categories require the subjunctive. The fourth — affirmative speech and thought verbs — requires the indicative.
The Two-Subject Rule
The subjunctive is only used when the two clauses have different subjects. If both clauses share the same subject, the infinitive replaces the clause.
| Two subjects | Same subject |
|---|---|
| Quiero que tú vengas. | Quiero venir. |
| Él pide que yo lo haga. | Él pide hacerlo. |
| Sentimos que ellos no puedan venir. | Sentimos no poder venir. |
The two-subject rule applies to all four trigger categories.
Affirmative vs Negative Speech and Thought Verbs
This is the most tested distinction at B2. Affirmative speech and thought verbs take the indicative. Negative speech and thought verbs take the subjunctive.
| Main verb | Mood | Example | Translation |
|---|---|---|---|
| Creer (affirmative) | Indicative | Creo que viene. | I think he is coming. |
| No creer (negative) | Subjunctive | No creo que venga. | I don’t think he is coming. |
| Pensar (affirmative) | Indicative | Pienso que es verdad. | I think it’s true. |
| No pensar (negative) | Subjunctive | No pienso que sea verdad. | I don’t think it’s true. |
| Decir (affirmative) | Indicative | Dice que viene. | He says he is coming. |
| Negar (negative) | Subjunctive | Niega que venga. | He denies that he is coming. |
The affirmative form asserts a fact, so it takes the indicative. The negative form denies or doubts the fact, so it takes the subjunctive.
The Infinitive Replacement
When both clauses share the same subject, the que clause is replaced by the infinitive.
| With que clause | With infinitive |
|---|---|
| Quiero que yo vaya. (incorrect) | Quiero ir. |
| Él pide que él lo haga. (incorrect) | Él pide hacerlo. |
| Sentimos que nosotros no podamos venir. (incorrect) | Sentimos no poder venir. |
The infinitive replacement is required, not optional. Using the que clause with the same subject is a common B2 error.
Fixed Expressions
| Expression | Meaning | Note |
|---|---|---|
| Quiero que… | I want you to… | Will, two subjects |
| Me alegra que… | I’m glad that… | Emotion |
| Dudo que… | I doubt that… | Doubt |
| No creo que… | I don’t think that… | Negative thought |
| Es posible que… | It’s possible that… | Evaluation |
| Es una pena que… | It’s a shame that… | Evaluation |
