Spanish Subjunctive: Doubt, Disbelief, and Denial

Lesson 13.213.2: The Subjunctive with Doubt, Disbelief, and Denial

The subjunctive mood is employed to communicate uncertainty, lack of belief, or the rejection of a statement within a subordinate clause. This grammatical structure typically consists of a main clause, a connector (queque), and a subordinate clause. For the subjunctive to be triggered, there generally must be a change of subject between the main and subordinate clauses, and the main clause must imply negation or uncertainty.

Essential Sentence Components

A sentence utilizing the subjunctive for doubt or denial follows this hierarchical structure:

  1. Main Clause: Contains an expression of doubt, disbelief, or denial.

  2. Connector: The word queque.

  3. Subordinate Clause: Contains the verb in the subjunctive mood.

Examples of Structure:

  • Main Clause: Dudo muchoDudo\,mucho | Connector: queque | Subordinate Clause: esteˊ enfermo.est\acute{e}\text{ enfermo}.

  • Main Clause: DudanDudan | Connector: queque | Subordinate Clause: su hijo les diga la verdad.su\,hijo\,les\,diga\,la\,verdad.

Expressions of Doubt, Disbelief, and Denial

The following verbs and impersonal expressions trigger the use of the subjunctive in the subordinate clause because they establish a lack of certainty or direct denial:

  • dudar: to doubt

  • negar (e:ie): to deny

  • no creer: not to believe

  • no estar seguro/a (de): not to be sure (of)

  • no es cierto: it's not true; it's not certain

  • no es seguro: it's not certain

  • no es verdad: it's not true

  • es improbable: it's improbable

  • es imposible: it's impossible

  • (no) es posible: it's (not) possible

  • (no) es probable: it's (not) probable

Contextual Examples:

  • Denial of Environmental Pollution: El gobierno niega que el agua esteˊ contaminada.El\,gobierno\,niega\,que\,el\,agua\,est\acute{e}\,contaminada. (The government denies that the water is polluted.)

  • Doubt of Resolution: Dudo que el gobierno resuelva el problema.Dudo\,que\,el\,gobierno\,resuelva\,el\,problema. (I doubt that the government will solve the problem.)

  • Specific Interaction: Daniel, no creo que debas darles comida a los peces.Daniel,\,no\,creo\,que\,debas\,darles\,comida\,a\,los\,peces. (Daniel, I don't think you should give food to the fish.)

The Rule of Subject Change and the Infinitive

A critical requirement for the subjunctive is a change of subject across clauses. If the subject remains the same throughout the sentence, the infinitive is used instead of the subjunctive, often omitting the connector queque.

Same Subject Examples:

  • Personal perspective: Dudo llegar temprano.Dudo\,llegar\,temprano. (I doubt I will arrive early.)

  • Third-party perspective: Mauricio duda llegar temprano.Mauricio\,duda\,llegar\,temprano. (Mauricio doubts he will arrive early.)

Nuances in Probability and Adverbs

There is a notable distinction between English and Spanish regarding probability. In English, stating something is "probable" or "possible" often suggests a high degree of certainty. However, in Spanish, the expressions es probablees\,probable and es posiblees\,posible imply inherent uncertainty and therefore trigger the subjunctive.

Examples of Probability:

  • Es posible que haya menos bosques y selvas en el futuro.Es\,posible\,que\,haya\,menos\,bosques\,y\,selvas\,en\,el\,futuro. (It's possible that there will be fewer forests and jungles in the future.)

  • Es muy probable que contaminemos el medio ambiente.Es\,muy\,probable\,que\,contaminemos\,el\,medio\,ambiente. (It's very probable that we're polluting the environment.)

Uncertain Adverbs: The adverbs Quiz\acute{a}s and tal vez (both meaning "perhaps" or "maybe") imply an uncertain possibility and are usually followed by the subjunctive.

  • Quizaˊs haga sol manˊana.Quiz\acute{a}s\,haga\,sol\,ma\acute{n}ana. (Perhaps it will be sunny tomorrow.)

  • Tal vez veamos la luna esta noche.Tal\,vez\,veamos\,la\,luna\,esta\,noche. (Perhaps we will see the moon tonight.)

Expressions of Certainty and the Indicative

When the main clause expresses belief, certainty, or truth, it no longer triggers the subjunctive. In these cases, the indicative mood must be used in the subordinate clause.

Expressions of Certainty:

  • no dudar: not to doubt

  • no cabe duda de: there is no doubt

  • no hay duda de: there is no doubt

  • no negar (e:ie): not to deny

  • creer: to believe

  • estar seguro/a (de): to be sure (of)

  • es cierto: it's true; it's certain

  • es verdad: it's true

  • es seguro: it's certain

  • es obvio: it's obvious

Examples of Certainty:

  • No negamos que hay demasiados carros en las carreteras.No\,negamos\,que\,hay\,demasiados\,carros\,en\,las\,carreteras. (We don't deny that there are too many cars on the highways.)

  • Es cierto que los tigres estaˊn en peligro de extincioˊn.Es\,cierto\,que\,los\,tigres\,est\acute{a}n\,en\,peligro\,de\,extinci\acute{o}n. (It's certain that tigers are in danger of extinction.)

Distinction Between Creer and No Creer

The verb creercreer (to believe) inherently expresses a belief or certainty, whereas no creerno\,creer implies doubt. This distinction significantly changes the mood required in the following clause.

  • Affirmative Belief (Indicative): Creo que debemos usar exclusivamente la energıˊa solar.Creo\,que\,debemos\,usar\,exclusivamente\,la\,energ\acute{\imath}a\,solar. (I believe we should exclusively use solar energy.)

  • Lack of Belief (Subjunctive): No creo que haya vida en el planeta Marte.No\,creo\,que\,haya\,vida\,en\,el\,planeta\,Marte. (I don't believe that there is life on the planet Mars.)
