Introduction
We use the second conditional to describe a situation in the present that is not real and the result if we imagine it is real.
If I took the bus, I would arrive at 7pm.
"If I took the bus" is a situation in the present that is not real. "I would arrive at 7pm" is the result if I imagine that the situation is real. Examples:
If I owned that house, I would paint it a different colour. I don’t own that house so painting it a different colour is an imagined result.
If I lived in Italy, I would learn to cook Italian food. I don’t live in Italy so learning to cook Italian food is an imagined result.
If Tom were rich, he would buy an expensive car. Tom is not rich so buying an expensive car is an imagined result.
If you were me, would you take the train or the bus? You are not me. What is your advice if you imagine that you are?
Form - conditional and main clause
We form the second conditional with a conditional clause and a main clause:
Conditional clause: "if" + past simple Main clause: "would" + infinitive (without "to") The order of the clauses does not matter: the meaning is the same.
If we put the conditional clause before the main clause, we use a comma:
We do not use a comma if we put the main clause before the conditional clause:
We only use "were" (not "was") for the past simple of "be" in the conditional clause.
We can contract the subject pronoun and "would": "I’d" / "you’d" / "we’d" / "they’d" / "she’d" / "he’d" / "it’d"
We can use the past continuous in the conditional clause: If I were being honest, I would tell him that I don’t like the food.
I am not being honest so I have not told him that I don’t like the food.
