Subjunctive Helper
The subjunctive explained: the triggers — wishes, doubts, emotions, impersonal expressions — and the full table for any verb.
When is the subjunctive required?
| Trigger | Pattern | Why |
|---|---|---|
| Wishes and hopes | Quiero que… / Espero que… | When you want someone else to do something, the second verb goes in the subjunctive. |
| Doubt and denial | No creo que… / Dudo que… | Belief takes the indicative; doubt and denial take the subjunctive. |
| Emotions and reactions | Me alegro de que… / Es triste que… | How you feel about something triggers the subjunctive. |
| Impersonal expressions | Es importante que… / Es necesario que… | Es + adjective + que is one of the most common subjunctive triggers. |
| Unknown or non-existent antecedents | Busco un libro que… | When you are looking for something that may not exist, the relative clause takes the subjunctive. |
The shortcut: if the sentence has two clauses, two different subjects, and the first clause expresses a wish, a doubt, an emotion or an impersonal judgement — the second verb is subjunctive. If there is only one subject, use the infinitive instead.
