Second conditional in English: structure, examples and exercises
The second conditional helps you talk about hypothetical situations, advice, dreams and unlikely results in the present or future.
Once the second conditional feels natural, you stop translating and start imagining in English.
Quick answer
The most common second conditional structure is If + past simple, would + infinitive. Use it for unreal, unlikely or hypothetical situations.
What is the second conditional?
The second conditional describes an imaginary condition and its possible result. It is the structure you use for sentences such as if I had..., if I could... or if I were....
Although it uses past simple after if, it usually does not refer to the past. The past form creates distance: the situation feels unreal, unlikely or imagined.

Second conditional structure
The second conditional structure combines an if + past simple clause with a main clause using would, could or might + infinitive.
| Type | Formula | Example |
|---|---|---|
| Affirmative | If + subject + past simple, subject + would + infinitive | If I knew the answer, I would tell you. |
| Negative | If + subject + did not + infinitive, subject + would not + infinitive | If she did not work so much, she would travel more. |
| Question | Would + subject + infinitive + if + subject + past simple? | Would you move abroad if you found a job? |
| Advice | If I were you, I would + infinitive | If I were you, I would start today. |
Comma rule: when the sentence starts with the condition, use a comma before the result; when it starts with the result, you usually do not need one.

Difference between first, second and third conditional
The difference is not only in the verb form, but also in the intention: a real probability, a present or future hypothesis, or an impossible past situation.
Real possibility
Imaginary situation
Past impossible result
Past condition, present result
Common second conditional mistakes
Avoid three mistakes: using would after if, confusing a hypothesis with a real possibility and forgetting that were is the safest form in If I were you.
