Present Subjunctive
Expressing Subjective or Uncertain Actions and States
The rule at a glance

I want, I hope
Quiero que vengas a la fiesta.

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

Structure & Formation
How to Form the Present Subjunctive
Formation Steps
- Start with the yo form of the present indicative (e.g., hablo, como, vivo)
- Drop the -o ending (e.g., habl-, com-, viv-)
- Add the "opposite vowel" endings:
- -ar verbs use -e endings (like -er verbs)
- -er/-ir verbs use -a endings (like -ar verbs)

Subjunctive with Uncompleted Action Connectors
Certain connecting phrases (conjunctions) always require the subjunctive because they introduce actions that haven't happened yet or may not happen at all.
Always + Subjunctive Connectors
Subjunctive or Indicative Connectors (Depends on Context)
These connectors take subjunctive when referring to a future or hypothetical action, but indicative when referring to a habitual or past completed action.
Subjunctive with Indefinite Antecedent
When describing something that may or may not exist, use the subjunctive. When referring to something known to exist, use the indicative.
Other Subjunctive Triggers
Quizá(s) / Tal vez (Perhaps / Maybe)
These words express uncertainty and trigger the subjunctive:
Aunque (Even if / Even though)
Aunque + subjunctive = hypothetical ("even if"). Aunque + indicative = known fact ("even though").

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.
