Conditionals

Conditionals = if-zinnen

A conditional sentence exists of 2 parts: 

If it rains tomorrow, I will stay at home

• the condition (voorwaarde/actie): If it rains tomorrow
• the result (resultaat/gevolg): I will stay at home.

There are 4 different ways to construct conditional sentences in English. We will look at all of them.

Zero conditional (100% waar):

This form is used for: 

- facts /  real (factual) situations in the present

- commands / the imperative form

How to make:  use a present simple in both parts

If water freezes, it becomes ice.

If you want to be better at English, pay attention (imperative)

In this conditional, you can replace the word 'if' with 'when' without changing the meaning.

 First conditional (erg waarschijnlijk, bijna 100% waar)

The type 1 conditional is used to refer to:

- the present or future where a situation is real

- a possible condition and its likely result

How to make: use a present simple in the if-clause

and the future simple in the main clause.

Future simple: will +  infinitive (full verb)

If you are late, she will be very angry.

Second conditional (onwaarschijnlijk, maar niet onmogelijk) 

The type 2 conditional is used to refer to:

- a hypothetical condition and its probable result (aka: 

its unlikely to happen, but not impossible)

How to make: use a past simple in the if-clause

and would + infinitive in the main clause.

If I learned to play the guitar, I would be  rock star.

If I were famous, I would post on Instagram every day!

In the if-clause, were is often used instead of was
