The subjunctive is a mood, not a tense — it expresses the speaker's attitude toward situations that are uncertain, hypothetical, desired, or emotional. It has four tenses (present, past, present perfect, past perfect) and is the most variable concept in Spanish.
|
|
|
|
## Key Rules
|
|
|
|
### How to spot a subjunctive sentence
|
|
1. **Construction:** `S/V + que + S/V` (subject-verb + que + subject-verb), OR a fixed main clause + `que` + subject-verb.
|
|
2. **The first verb must come from W.E.I.R.D.:**
|
|
- **W**ill (querer, preferir, necesitar, desear)
|
|
- **E**motion (esperar, gustar, tener miedo)
|
|
- **I**nfluence (insistir en, desear)
|
|
- **R**ecommendation/Request (recomendar, sugerir, aconsejar)
|
|
- **D**oubt / Disbelief / Denial (dudar, negar, no pensar, no creer)
|
|
3. **The second verb (after `que`) is conjugated in the subjunctive** — irregularly, depending on the tense.
|
|
4. The two clauses usually have **different subjects**.
|
|
|
|
### Verbs that DO NOT trigger the subjunctive
|
|
- `creer que` (to believe), `saber que` (to know factually), `es un hecho que` (it's a fact that) — these state facts/opinions, not WEIRD categories.
|
|
|
|
### Impersonal expressions that trigger the subjunctive
|
|
- Es necesario que… — It's necessary that
|
|
- Es importante que… — It's important that
|
|
- Es urgente que… — It's urgent that
|
|
- Es bueno / mejor / malo / triste que… — It's good / better / bad / sad that
|
|
- Ojalá (que)… — I hope / hopefully
|
|
|
|
## Conjugation / Pattern Tables
|
|
|
|
### The four subjunctive tenses
|
|
| Tense | Used for |
|
|
|---|---|
|
|
| Present subjunctive | Present/future actions after WEIRD trigger |
|
|
| Imperfect (past) subjunctive | Past actions, contrary-to-fact `si` clauses |
|
|
| Present perfect subjunctive | Recently completed actions |
|
|
| Pluperfect subjunctive | Past hypotheticals (would have…) |
|
|
|
|
## Examples
|
|
| Spanish | English | Subjunctive? |
|
|
|---|---|---|
|
|
| Yo creo que tú comiste. | I believe that you ate. | No (creer = opinion) |
|
|
| Yo sé que tú comiste. | I know that you ate. | No (saber = factual) |
|
|
| Es un hecho que tú comiste. | It's a fact that you ate. | No (statement of fact) |
|
|
| Yo quiero que tú estudies. | I want you to study. | Yes (querer = Will) |
|
|
| Es necesario que estemos aquí. | It's necessary that we be here. | Yes (impersonal trigger) |
|
|
|
|
## Notes & Gotchas
|
|
- Same-subject sentences usually drop `que` and use the infinitive: *Yo quiero estudiar* (not *que yo estudie*).
|
|
- Vosotros forms exist but are rarely needed in Latin American Spanish.
|
|
- The subjunctive isn't a tense — it's a *mood* that overlays the tense system.
