How do you use the subjunctive in Spanish?
The Spanish subjunctive is not a tense like past or present, but a mood that reflects how the speaker feels about an action. You use it to express doubt, desire, emotion, or uncertainty rather than objective facts. Think of the indicative mood as a news reporter stating confirmed events, while the subjunctive mood is an opinion columnist sharing wishes, hopes, or fears about those events. You will almost always see it in a two-part sentence connected by the word que (that).
What is the subjunctive mood?
In Spanish grammar, a mood shows the speaker's attitude toward what they are saying. The indicative mood states facts and reality (e.g., You study). The subjunctive mood expresses subjectivity, uncertainty, or unrealized actions (e.g., I want you to study). It is typically found in a dependent clause when the main clause expresses a subjective view.
The WEIRDO acronym
To remember when to trigger the subjunctive, use the WEIRDO acronym: Wishes, Emotions, Impersonal expressions, Recommendations, Doubt, and Ojala. If the main clause fits one of these categories, and there is a subject change after the word que, the following verb must be in the subjunctive. For example, Espero que (I hope that) triggers it because it is a Wish.
How to form the present subjunctive
To conjugate regular verbs in the present subjunctive, start with the yo form of the present indicative, drop the -o, and add the opposite endings. For -ar verbs, use -e, -es, -e, -emos, -en. For -er and -ir verbs, use -a, -as, -a, -amos, -an. For example, hablar becomes hable and comer becomes coma.
Where students slip up
A common mistake is using the subjunctive when there is no change of subject. If you are expressing a wish or emotion about yourself, you use the infinitive, not the subjunctive. For example, Quiero comer (I want to eat) uses the infinitive, but Quiero que comas (I want you to eat) uses the subjunctive because the subject changes from I to you.
Worked through
Translate I recommend that he reads the book into Spanish, deciding whether to use the indicative or subjunctive.
First, check for a trigger. I recommend (Recomiendo) is a Recommendation, which falls under the WEIRDO acronym. Second, check for a subject change. The first subject is I and the second is he (el), connected by que. Since there is a WEIRDO trigger and a subject change, we must use the subjunctive for the verb to read (leer). The yo form of leer is leo. We drop the -o and add the opposite ending for an -er verb in the el/ella form, which is -a. The subjunctive form is lea. The final sentence is: Recomiendo que el lea el libro.
