Present Subjunctive
Expressing Subjective or Uncertain Actions and States
What You'll Learn
Overview
The subjunctive is a mood (not a tense) used to express subjective or uncertain actions and states. Unlike the indicative mood which expresses facts and certainty, the subjunctive expresses emotions, doubts, wishes, and possibilities.
Indicative (Facts)
Subjunctive (Doubt)
Key Concept: Two Subjects Required
The subjunctive nearly always requires two different subjects connected by "que":
Yo quiero que tú vengas (I want YOU to come) ✓ Subjunctive
Yo quiero venir (I want to come - same subject) ✗ No subjunctive, use infinitive

Common Mistakes
Same Subject = Infinitive
When the subject is the same, use the infinitive, not subjunctive.
Forgetting "que"
Don't forget "que" to connect the clauses (except with Ojalá).
Creo que + Subjunctive
"Creo que" expresses certainty, so use indicative.
Wrong Endings
-ar verbs use -e endings, -er/-ir verbs use -a endings.
