Purpose

By the end of this lesson, you will be able to correctly trigger the subjunctive in sentences expressing wishes, doubt, and emotion.

Lesson Explanation

Building on the previous lesson, the subjunctive appears when the main clause expresses one of a few genuinely specific categories, followed by que and a different subject in the subordinate clause.

Wishes/influence — verbs like querer (to want), esperar (to hope), pedir (to ask):

Espero que vengas. — I hope you come.
Quiero que estudies más. — I want you to study more.

Doubt/denial — dudar (to doubt), no creer (to not believe), no pensar (to not think):

Dudo que sea verdad. — I doubt it is true.
No creo que venga. — I don't think he/she is coming.

Emotion — alegrarse de (to be glad), sentir (to be sorry/feel), temer (to fear):

Me alegro de que estés aquí. — I'm glad you are here.
Siento que no puedas venir. — I'm sorry you can't come.

A genuinely important flip: when the same verb expresses certainty rather than doubt, the indicative is used instead. Compare No creo que venga. (subjunctive, doubt) with Creo que viene. (indicative, “I believe” expresses genuine certainty, not doubt). This certainty/doubt switch is one of the single most reliable tests for whether the subjunctive is required.
