Conditionals – First, Second and Third

If you could become fluent in any language, which language would you choose?
I hope you said English! If you didn’t, that is quite alright too.
Learning a new language takes time and effort but it’s well worth it.

It is particularly important to learn grammar that we use in everyday language.

You’ve probably heard of conditionals before. Well we are going to review them in this blog post.
We will talk about:

The First conditional
The second conditional
The third conditional

The First conditional - Future possibilities

The First Conditional is about future possibilities, things that may or may not happen in the Future depending on a certain circumstance or condition.

Supposing your friend asks you to play football tomorrow and you really want to play but can only go depending on work, you might say:

If I have no work tomorrow, I’ll play football.

This suggests that you won’t play football if you need to work.

Look at some more possible examples:

If you give me a lift, I will go to your party . ( Going to the party depends on a lift)

If you buy her dinner, she will help you . ( Her help  is conditional on you paying for the dinner)

We form the first conditional: If +present simple, will/won’t  + infinitive

We can also put the if clause  after the will clause : will + infinitive + if + present simple

We will pass the test if we study. (Passing the test is conditional on studying)


Note: If we put ‘if’ at the beginning of the sentence, we need to use a comma after the ‘if’ clause.

The First conditional

We use the first conditional to talk about a real possibility in the future

If + present + will/won’t + infinitive

The Second conditional - Imaginary situations

We use the Second conditional for imaginary or hypothetical situations that could be now or in the future.

We often think and talk about what we would do if we had a million euro:

If I were a millionaire, I would buy a big house.

The present reality is that I am not a millionaire, and so I cannot buy a big house. I am just dreaming.

Take a look at some more examples:

If she won the lottery, she would buy a Ferrari.

If I was British, I could speak English fluently.

If I were on holidays, I would be on a beach.

To form the second conditional we use : If + past simple + would do/infinitive

The Second conditional

We use the second conditional to talk about imaginary situations.

If + past simple + would/wouldn’t + infinitive

The Third conditional

We use the third conditional to talk about imaginary situations in the past. In other words, things that didn’t happen in the past but could have happened if the situation was different.

If I didn’t get much sleep because I went to bed late, I can say:

If I had gone to bed earlier last night, I would have slept more.

The third conditional expresses how things could have been.

Check out some more examples:

If I had studied harder, I would have passed the test.

If he hadn’t called the doctor, he would not have got the medicine.

If they had saved some money, they would have bought a house.

To make the third conditional we use: If + past perfect + would/wouldn’t have + past participle

The Third conditional

We use the third conditional to talk about imaginary situations in the past.

If + past perfect + would/wouldn’t have + past participle

Test Yourself

Use the 1st, 2nd or 3rd conditional to make a sentence for each of these situations.

Example: Andrew arrived at the airport late and missed the flight.

Answer: If Andrew had arrived at the airport early, he wouldn’t have missed his flight.

  1. I will go to her party on condition that I have a lift.
  2. I would buy a big house on condition that I won the lottery.
  3. Nikola is very tired today as she went to bed late last night.
  4. Marina didn’t get married to the man because she didn’t love him.
