Introduction to the Spanish Subjunctive

Grade 8 · Spanish · Study Guide

A beginner's guide to understanding when and how to use the subjunctive mood in Spanish.

In Spanish, verbs can appear in different moods. The indicative mood is used to state facts and certainties — things that are real and known. The subjunctive mood is different: it is used to express doubt, wishes, emotions, hypothetical situations, and recommendations. Learning the subjunctive is a major step forward in Spanish fluency.

The present subjunctive is formed by taking the yo form of the present indicative, dropping the -o, and adding the opposite endings. For -AR verbs, use the endings -e, -es, -e, -emos, -éis, -en. For -ER and -IR verbs, use -a, -as, -a, -amos, -áis, -an.

For example: hablar → yo hablo → drop -o → habl- → add subjunctive endings: hable, hables, hable, hablemos, habléis, hablen.

The subjunctive is most often triggered by certain phrases. Common triggers include: quiero que (I want that), espero que (I hope that), es importante que (it is important that), and ojalá (hopefully/I hope). These are followed by a new subject and the subjunctive form of the second verb.

Example: Quiero que tú estudies. (I want you to study.) Notice there are two subjects — yo (implied) and tú — which is a key signal to use the subjunctive.
