What would you do if you won the lottery? Where would you live if you could choose anywhere in the world? These questions feel different from "real" possibilities — they're imaginary, unlikely, or just for fun. English uses the second conditional for exactly this: situations we're presenting as hypothetical rather than genuinely expected.
Quick form: If + past simple, would + base verb → If I had more time, I would learn Japanese. I would travel more if I didn't have so much work.
What the second conditional expresses
The second conditional presents a situation as imaginary, remote, tentative, or unlikely — not as a normal expected future event:
- Imaginary present situations: If I were you, I would apologise.
- Unlikely future scenarios: If it snowed in July, we would be amazed.
- Dreams and wishes: If I had a boat, I would sail around the world.
- Hypothetical questions: What would you do if you won first prize?
The key idea is that the speaker is not predicting — they're inviting you into an imaginary world.
Forming the second conditional
| Clause | Tense / Form | Example |
|---|---|---|
| If clause | past simple | If I had a car… |
| Result clause | would + base verb | …I would drive to the coast. |
The if-clause uses a past form — usually the past simple, but also were with be and past modal forms such as could. Even though the situation refers to now or the future, the past form is the classic signal that the situation is imaginary rather than real.
The result clause uses would + base verb (often contracted to 'd):
- If she lived closer, we would see her more often.
- If they offered me the job, I'd take it.
Comma rule: when the if-clause comes first, a comma follows it. When the result clause comes first, no comma is needed.
Would or wouldn't in the result clause
To make the result negative, use wouldn't (would not):
- If I had more money, I wouldn't worry so much.
- If she could speak French, she wouldn't need a translator.
You can also make the if-clause negative with standard past-tense negatives — didn't, wasn't/weren't, couldn't, etc.:
- If it didn't rain so often here, more tourists would visit.
- If we weren't so busy, we would help.
Both clauses can be negative:
- If I didn't feel tired, I wouldn't cancel.
Other modals: could and might
Would is the default in the result clause, but could and might are also common:
| Modal | Effect | Example |
|---|---|---|
| would | the speaker's default hypothetical result | If I had the time, I would read more. |
| could | hypothetical ability or permission | If I had the time, I could read more. |
| might | possible but uncertain hypothetical result | If I had the time, I might read more. |
Could shifts the focus to ability in the imagined scenario. Might signals that even in the imagined world the result isn't guaranteed.
If I were or if I was?
In hypothetical second conditional sentences with the verb be, formal English usually uses were for all persons — including I, he, she, it:
- If I were richer, I'd donate more.
- If she were here, she'd know what to do.
This is called the subjunctive and sounds more careful and formal. In everyday spoken English, if I was is also very common and widely accepted:
- If I was in charge, I'd do things differently. (natural in speech)
The phrase "If I were you…" (offering advice) is fixed and essentially always uses were — you will rarely hear "if I was you" in standard usage.
In hypothetical second conditional sentences, were is the safest formal choice; was is common in informal speech with I/he/she/it. For exams or formal writing, were is always the safer option.
Questions in the second conditional
You can form second-conditional questions by placing the modal auxiliary (would, could, might) before the subject in the main clause:
- If you could live anywhere, where would you live?
- Would you mind if I asked you a favour?
- If she offered you the role, would you accept it?
The if-clause itself stays in the past form — the inversion happens in the main clause only.
Second conditional vs. first conditional
These two conditionals look similar but carry very different meanings:
| First conditional | Second conditional |
|---|---|
| If it rains, we will cancel the picnic. | If it snowed here, the office would close. |
| Real/possible future situation | Imaginary or unlikely situation |
| If + present simple, will + base verb (most common pattern) | If + past simple, would + base verb |
| The speaker thinks it could genuinely happen | The speaker is imagining a hypothetical world |
The clearest signal is the verb form in the if-clause: present simple (first) vs. past simple (second). See the first conditional and zero conditional articles for comparison.
At B2, the third conditional handles imaginary past situations ("If I had studied harder, I would have passed") — that's covered in Third conditional at B2.
Common mistakes
- ❌ If I would have more money, I would travel. → ✅ If I had more money, I would travel. (in the basic second conditional, would belongs in the result clause, not the if-clause — use past simple: If I had…)
- ❌ If I had more time, I will finish it. → ✅ If I had more time, I would finish it. (will belongs to the first conditional; the second conditional takes would)
- ❌ If she was more careful, she wouldn't do such mistakes. → ✅ If she were / was more careful, she wouldn't make such mistakes. (make a mistake, not do — and were is the formal choice)
- ❌ What you would do if you lost your passport? → ✅ What would you do if you lost your passport? (the modal auxiliary comes before the subject in the main clause to form the question)
Quick check
Choose the correct form, rewrite the sentence, or answer the question:
- If I ____ (have / had / would have) more time, I would exercise every day.
- If she spoke Italian, she ____ (will get / would get / gets) the job easily.
- Rewrite correctly: If I would be you, I would apologise.
- If I were or If I was — which is more formal?
- What's the difference? a. If you study hard, you'll pass. b. If you studied hard, you'd pass.
Show answers
- had — past simple in the if-clause for a hypothetical situation; would have in the if-clause is the most common mistake with this conditional
- would get — result clause uses would + base verb; will belongs to the first conditional (real future possibility)
- ✅ If I were you, I would apologise. — no would in the if-clause; use past simple (subjunctive were preferred here)
- If I were is more formal; if I was is acceptable in everyday speech but avoid it in exams or formal writing
- a. First conditional — real possibility (speaker thinks studying hard is genuinely possible); b. Second conditional — imaginary or unlikely scenario (speaker is presenting it as hypothetical, perhaps suggesting the person is not studying)
Key takeaways
- The second conditional uses if + past simple in the condition clause and would + base verb in the result clause.
- Use it for imaginary, hypothetical, or unlikely present/future situations — the speaker is not predicting but imagining.
- In the basic second conditional, would belongs in the result clause, not the if-clause — writing If I would have… instead of If I had… is the single most common mistake.
- If I were you… is a fixed phrase for advice; were is the formal choice in hypothetical second conditional sentences, though was is common in casual speech with I/he/she/it.
- Could (hypothetical ability) and might (uncertain result) can replace would in the result clause.
- The if-clause can come first (with a comma) or second (no comma) — both are correct.
- Compare with the first conditional (real future possibilities: if + present simple, will) and the third conditional (imaginary past situations, B2).
