Expressing Doubt and Denial with the Subjunctive

Expressing Doubt and Denial with the Subjunctive


The subjunctive is one of the three moods in Spanish, the other two being the indicative (actions, events, facts) and the imperative (commands). You can find more on the differences between the subjunctive and the indicative here!


Many of the verbs and phrases that require the subjunctive fit into the acronym WEIRDO: Wishes, Emotions, Impersonal expressions, Recommendations, Doubt/Denial and Ojalá. In this article, we're going to take a look at doubt and denial.


To doubt or deny something is to question its connection with reality or to express that it is hypothetical.

I doubt that he has my phone number.
No parece que vaya a mejorar la situación.
It doesn't appear that the situation will improve.
