IntermediateSubjunctive Mood
How the subjunctive expresses doubt, desire, emotion and unreality in Spanish, English and Chinese.
Compare languages
Spanish uses the subjunctive extensively across many contexts. English preserves it only in fossilized forms (were, be, that he speak). Chinese has no subjunctive — context and adverbs handle the meaning.
Overview
The subjunctive mood expresses actions that are not objective reality — wishes, doubts, emotions, possibilities, and hypotheticals.
- Spanish: The subjunctive is ubiquitous. It appears in dependent clauses after triggers of doubt, desire, emotion, impersonal expressions, and relative clauses with uncertain antecedents. Spanish learners must master the subjunctive to speak naturally.
- English: The subjunctive is barely alive. It survives in a few fossilized forms: If I were…, I demand that he be…, It is important that she speak…. Modern English uses modal verbs and periphrasis instead.
- Chinese: Has no subjunctive whatsoever. The same sentence structures express real and unreal situations. Context, adverbs, and particles make the distinction.
Spanish
Present subjunctive
Formed from the yo form of the present indicative:
| Verb | yo form | Subjunctive stem | Present subjunctive (tú) |
|---|---|---|---|
| hablar | hablo | hable- | hables |
| comer | como | coma- | comas |
| vivir | vivo | viva- | vivas |
| tener | tengo | teng- | tengas |
| ir | voy | vay- | vayas |
| ser | soy | sea- | seas |
Rule: For -ar verbs, use -e endings. For -er/-ir verbs, use -a endings. (Opposite of indicative.)
Imperfect subjunctive
Formed from the third-person plural preterite:
| Verb | 3rd pl preterite | Imperfect subjunctive (yo) |
|---|---|---|
| hablar | hablaron | hablara or hablase |
| comer | comieron | comiera or comiese |
| vivir | vivieron | viviera or viviese |
Two forms: -ra and -se are interchangeable. -ra is more common.
When to use the subjunctive
1. Doubt and uncertainty
- Es posible que llueva. (It might rain.)
- No creo que venga. (I don’t think he’s coming.)
- Dudo que sea verdad. (I doubt it’s true.)
Note: With certainty, use indicative:
- Creo que viene. (I think he’s coming. — indicative, no subjunctive)
2. Desire and will
- Quiero que vengas. (I want you to come.)
- Espero que estés bien. (I hope you’re well.)
- Prefiero que no lo hagas. (I’d rather you didn’t do it.)
3. Emotion
- Me alegro de que vengas. (I’m glad you’re coming.)
- Temo que sea tarde. (I’m afraid it’s late.)
- Es triste que no pueda venir. (It’s sad that she can’t come.)
4. Impersonal expressions
- Es necesario que estudies. (It’s necessary that you study.)
- Es importante que sepas esto. (It’s important that you know this.)
- Es mejor que vayamos pronto. (It’s better that we go soon.)
Rule: If the expression implies certainty (es cierto, es obvio), use indicative. If it implies subjectivity (es posible, es importante), use subjunctive.
5. Relative clauses (uncertain antecedent)
- Busco una persona que hable español. (I’m looking for someone who speaks Spanish. — subjunctive: such a person may not exist)
- Conozco a una persona que habla español. (I know someone who speaks Spanish. — indicative: the person exists)
6. Negative imperatives
- No vengas tarde. (Don’t come late.)
- No te preocupes. (Don’t worry.)
7. Hypothetical conditions
- Si tuviera dinero, viajaría. (If I had money, I would travel.)
- Si fuera tú, no lo haría. (If I were you, I wouldn’t do it.)
Sequence of tenses
| Main clause | Dependent clause |
|---|---|
| Present | Present subjunctive |
| Past / conditional | Imperfect or pluperfect subjunctive |
| Future | Present subjunctive (future subjunctive is archaic) |
English
Fossilized subjunctive forms
English preserves the subjunctive in only a few contexts:
1. Were in hypothetical conditionals
- If I were you… (all persons: If he were, If she were)
- I wish I were taller.
- If it were not for you…
Note: Many native speakers use was in informal speech, but were is standard.
2. Be in formal demands/suggestions
- I demand that he be punished.
- It is essential that she be informed.
- The judge ordered that the witness appear in court.
3. Base form after certain verbs
- I suggest that he leave immediately.
- It is important that everyone attend the meeting.
4. Fixed expressions
- God bless you.
- Long live the king.
- Heaven forbid.
- Come what may.
- Suffice it to say.
What English uses instead
English uses modals and periphrasis where Spanish uses the subjunctive:
| Spanish subjunctive | English equivalent |
|---|---|
| Quiero que vengas | I want you to come |
| Es posible que llueva | It might rain |
| Me alegro de que vengas | I’m glad you’re coming |
| No creo que sea verdad | I don’t think it’s true |
| Es necesario que estudies | You need to study |
If I was vs If I were
Formal: If I were you… (subjunctive)
Informal: If I was you… (indicative, increasingly accepted)
Recommendation: Use were in formal writing and exams.
Chinese
No subjunctive
Chinese has no grammatical mood corresponding to the subjunctive. The same structures express real and unreal situations.
How Chinese expresses subjunctive meanings
1. Modals for possibility/doubt
- 可能会下雨。(It might rain.)
- 我觉得他不会来。(I don’t think he’ll come.)
2. Periphrasis for desire
- 我想让你来。(I want you to come. — literally “I want make you come”)
- 希望你能来。(I hope you can come.)
3. Context for hypotheticals
- 如果我有钱，我就去旅行。(If I had money, I would travel.)
Same structure as a real condition:
- 如果明天下雨，我就不去。(If it rains tomorrow, I won’t go. — real condition, same structure)
4. Emotion verbs with indicative
- 我很高兴你能来。(I’m glad you can come.)
- 我担心他不会通过考试。(I’m afraid he won’t pass the exam.)
5. 要是 for stronger hypothetical
要是 implies a more hypothetical or counterfactual condition than 如果:
- 要是我当时学习了… (If I had studied then…)
Why Chinese has no subjunctive
Chinese grammar relies on:
- Context — the listener infers hypothetical from situation
- Adverbs — 可能, 也许, 要是 signal uncertainty
- Modals — 会, 能, 要 express attitude
- Particles — 了 marks change, 吧 softens
There is no grammatical requirement to mark unreality on the verb itself.

| Hypothetical | imperfect subjunctive | were / would | context + 如果/要是 |
