IntermediateConditionals
How if-clauses express hypothetical, probable, and impossible situations in Spanish, English and Chinese.
Compare languages
English uses three main conditional patterns. Spanish uses indicative or subjunctive depending on probability. Chinese keeps the same word order and uses particles or context to show hypothetical meaning.
Overview
Conditionals express what happens — or would happen — under certain circumstances.
- Spanish: Uses the indicative for real conditions and the subjunctive for hypothetical ones. The subjunctive is required in both the if-clause and the result clause for counterfactuals.
- English: Uses three main patterns (first, second, third conditional) plus mixed conditionals. No subjunctive, but uses past tense forms to indicate unreality.
- Chinese: Has no special conditional verb forms. Uses 如果 (if) + normal word order, with 就 (then) optionally marking the result.
Spanish
Spanish conditionals divide cleanly into real (indicative) and unreal (subjunctive + conditional).
Real conditions (indicative)
When the condition is possible or likely:
- Si llueve, me quedo en casa. (If it rains, I stay home.)
- Si vienes, tendrás comida. (If you come, you will have food.)
Rule: Both clauses use indicative. The result can be present, future, or imperative.
Hypothetical conditions (subjunctive + conditional)
When the condition is unlikely or contrary to fact:
- Si tuviera dinero, viajaría. (If I had money, I would travel.)
- Si supiera la verdad, lo entendería. (If I knew the truth, I would understand.)
Rule: If-clause uses imperfect subjunctive. Result uses conditional.
Past counterfactuals (pluperfect subjunctive + conditional perfect)
When the condition was not met in the past:
- Si hubiera estudiado, habría aprobado. (If I had studied, I would have passed.)
- Si me hubieras llamado, habría venido. (If you had called me, I would have come.)
Rule: If-clause uses pluperfect subjunctive. Result uses conditional perfect.
Mixed conditionals
Connecting past condition to present result:
- Si hubiera estudiado, sería médico. (If I had studied, I would be a doctor.)
Rule: Past condition (pluperfect subjunctive) + present result (conditional).
Word order
Spanish allows either clause first:
- Si llueve, me quedo. / Me quedo si llueve.
- Si tuviera dinero, viajaría. / Viajaría si tuviera dinero.
English
English uses four main conditional patterns based on probability and time.
Zero conditional (general truth)
If + present simple, present simple:
- If you heat ice, it melts.
- If I don’t sleep, I get grumpy.
Use: Facts, scientific truths, habits.
First conditional (real future)
If + present simple, will + infinitive:
- If it rains, I will stay home.
- If she calls, tell her I’m out.
Use: Probable future situations. Result can also be imperative.
Important: Never use will in the if-clause:
- ❌ If it will rain, I will stay.
- ✅ If it rains, I will stay.
Second conditional (unreal present/future)
If + past simple, would + infinitive:
- If I had a car, I would drive to work.
- If she knew, she would tell us.
Use: Hypothetical or unlikely situations. Past form indicates unreality.
Were for all persons:
- If I were you… (not If I was you)
- If he were here… (formal)
Third conditional (past counterfactual)
If + past perfect, would have + past participle:
- If I had studied, I would have passed.
- If they had arrived on time, they would have seen it.
Use: Regrets about the past. The condition was not met.
Mixed conditional
Past condition, present result:
- If I had studied medicine, I would be a doctor now.
Present condition, past result (less common):
- If I were more careful, I wouldn’t have broken it.
Chinese
Chinese conditionals use normal word order with 如果 (if) and optionally 就 (then).
Basic pattern: 如果…，(就)…
- 如果下雨，我就不去。(If it rains, I won’t go.)
- 如果你来，我就请你吃饭。(If you come, I’ll treat you to dinner.)
就 is optional but common. It marks the result clause.
Hypothetical conditions
Chinese has no special verb form for hypotheticals. Context makes it clear:
- 如果我有钱，我就去旅行。(If I had money, I would travel.)
The hypothetical meaning comes from context, not verb form. Adverbs help:
- 要是…就… (more hypothetical than 如果)
- 假如… (formal hypothetical)
Past counterfactuals
Use 如果 + 了 (completion) to show the condition was not met:
- 如果我那时候学习了，我就考上了。(If I had studied then, I would have passed.)
要是 as casual alternative
要是 is more colloquial than 如果:
- 要是你不来，我就自己去。(If you don’t come, I’ll go alone.)
Word order
Chinese allows either clause first:
- 如果…，… / …, 如果…
