First conditional vs second conditional
We use the first conditional to talk about possible situations, things that may easily happen. We use the second conditional to talk about unrealistic situations.
- If I see Sara, I’ll tell her to call you. (=possible)
- If I won the lottery, I’d buy a new house. (=unrealistic)
Sometimes we use either the first or second conditional, and we use one or the other depending on how probable we think the situations are to happen.
- If I find her, I’ll tell her that I love her. (=I think it’s possible that I find her)
- If I found her, I’d tell her that I love her. (=I think it’s improbable that I find her)
