The Second Conditional

The second conditional (also called conditional type 2) is a structure used for talking about unreal situations in the present or in the future. We are thinking about a particular condition in the future, and the result of this condition.

When to use the second conditional

We use the second conditional or type 2 conditional in two ways:

  1. To talk about events in the future that are probably not going to happen.
  2. To talk about impossible or unreal situations in the present (hypothetical).

The ‘if’ clause states the condition while the main clause states the result of the condition – if it were true.

  • If I won the lottery, I would buy a car.
  • I would be happy if I married Mary.

How to form the second conditional

Just like the first conditional, the second conditional is made up of two clauses:

  1. An ‘if’/condition clause
  2. A main/result clause

  • If it snowed this July (‘if’ clause/condition) + I would be so surprised. (main/result clause)
  • I would come in last (main/result clause) + if I ran a marathon. (‘if’ clause/condition)

The ‘if’ clause uses the Past Simple tense. The main clause (result clause) uses the Present conditional (would + verb) or Present Continuous conditional (would + be + -ing verb).

  • If I were you, I would wear a helmet. (condition = if I were you – which is untrue and impossible)
  • I would donate all my money to charity if I had millions of dollars. (condition = if I had millions of dollars – which is unlikely; result = I would donate all my money to charity.)
  • I would be having a good time if I met my friends.

The order of the clauses is not important. We can put the ‘if’ clause first or second. However, since the ‘if’ clause is a subordinate clause, (can’t stand alone as a full sentence), we should put a comma after the ‘if’ clause when it comes before the main clause (result clause).

  • If I could fly, I would fly around the world. (the ‘if’ clause is first, thus a comma follows)
  • I would end your pain if I had the cure for cancer. (the ‘if’ clause is second, thus no comma is needed)

We can also use modals (could, might, should) in the main clause of second conditional sentences.

  • If we made more money, we might take more vacations.
  • He couldn’t go to the concert if you gave him a ticket.
  • I could quit my job if I won the lottery.

We can make positive, negative, and interrogative sentences using the second conditional.

  • Jamie wouldn’t go if you invited him.
  • If we weren’t away, we would go to the party.
  • What would you do if a meteor hit the earth right now?
Note: The word ‘if’ is a common feature of conditional statements. However, it is also possible to use words like ‘provided’ and ‘as long as’ in conditional structures. We use them with similar meaning when we want to emphasize the condition. 

– Provided you pay me back soon (condition), I will lend you the money.
– I think I’ll continue studying English, as long as I have the time to do so (condition).
