Conditional clause - Voorwaardelijke bijzin

Introduction

Conditional clauses are used to to refer to hypothetical situations; things that could happen if certain criteria were met. These criteria are expressed by the conditional clause, whilst the main clause describes the hypothetical situation as such.

The main clause accompanying a conditional clause can be made with a main verb in the present tense or using the past tense of the modal verb zullen. Most of the time, the subordinating conjunction als (or indien for more formal language) is used to introduce the conditional clause.

The tense used in the conditional clause will determine how hypothetical the sentence is.

Conditional in the present tense

A conditional in the present tense describes a straightforward condition for something to happen in the future.

Als ik studeer voor mijn examen, haal ik een A.
If I study for my exam, I get an A.

Note that a present tense is used in both the subordinate clause and the main clause, even though the present tense of zullen plus an infinitive is also possible in the main clause.

Als ik studeer voor mijn examen, zal ik een A halen.
If I study for my exam, I will get an A.

Conditional in the past tense

Using a conditional in the past tense will make the situation in the main clause more hypothetical but not entirely unrealistic.

Als ik voor mijn examen studeerde, zou ik een A halen.
If I studied for my exam, I would get an A.

Note that in the subordinate clause the verb is in the past tense.

It is actually possible to have a conditional sentence without zou/zouden:

Als ik jou was, kocht ik een fiets.
If I were you, I would buy a bicycle.

The last example is an illustration of carefully phrased advice. This can also be used without als, when the context is clear, as you can see in the example below:

Wat zou jij doen als je de lotto won? What would you do if you won the lottery?
Ik zou een Porsche kopen. I would buy a Porsche.

Conditional in the pluperfect

When using a conditional in the pluperfect, the situation is no longer possible, as the condition was not fulfilled in the past.

Als ik voor mijn examen had gestudeerd, zou ik een A hebben gehaald.
If I had studied for my exam, I would have gotten an A.

Note that in the subordinate clause the verb is in the pluperfect tense.

It is actually possible to have a conditional sentence without zou/zouden:

Als ik jou was geweest, had ik niets gedaan.
If I had been you, I would have done nothing.

Condition without als

Sometimes the condition expresed by als can be omitted and its presence can be imagined.

Zou zij naar Antwerpen gaan (als zij geld had)?
Would she go to Antwerp (if she had money)?

Mjin ouders zouden op bezoek zijn gekomen (als ze tijd hadden gehad).
My parents would have visited me (if they had had time).
