Conditional clauses are a type of subordinate clause. In German, there are 5 types of conditional clauses:
| Type of conditional | Used for |
|---|---|
| Clause Type -1 Imperativ + Wenn + Präsens | Orders |
| Clause Type 0 Präsens + Wenn + Präsens | Scientific or empirical realities |
| Clause Type 1 Futur I + Wenn + Präsens | Possible Situations |
| Clause Type 2 Konjunktiv II Präteritum + Wenn + Konjunktiv II Präteritum | Imaginary situations in the present |
| Clause Type 3 Konjunktiv II Plusquamperfekt + Wenn + Konjunktiv II Plusquamperfekt | Imaginary Situations in the past |
Type -1 clauses are used for giving conditional orders and are formed:
Sag mir, wenn du Zeit hast
Tell me if you have time
Type 0 clauses are used to express empirical or scientific realities. They are constructed in the following way:
Du kannst alles schaffen, wenn du es wirklich willst
You can do it all, if you really want to
Remember that the order of the sentences can be reversed, but the verb must remain in the second position in the main clause:
Wenn du es wirklich willst, kannst du alles schaffen
If you really want to, you can do it all
Type 1 clauses are used to express events that might happen. Their construction:
Wenn ich Geld habe, werde ich einen neuen Laptop kaufen
When/If I have money, I will buy a new laptop
NOTE: The idea of this clause is that we think that we are going to have money in the future; we consider it to be a possible situation in the future.
Type 2 is used for narrating situations that have little possibility of taking place:
Konjunktiv II (Präteritum) + Wenn + Konjunktiv II (Präteritum)
Wenn ich Millionär wäre würde ich ein Motorrad kaufen
If I were a millionaire, I’d buy myself a motorcycle
Type 3 conditional clauses express situations that are not possible in the present, their construction is:
Konjunktiv II Plusquamperfekt + Wenn + Konjunktiv II Plusquamperfekt
Wenn ich an seiner Stelle gewesen wäre, hätte ich das selbe gemacht
If I had been in his place, I would have done the same
Conditional clauses can also be formed without the conjunction wenn but by changing the position of the verb to position 1.
Construction with wenn:
Wenn ich reich wäre, würde ich dir helfen
If I were rich, I would help you
Construction without wenn:
Wäre ich reich, würde ich dir helfen
If I were rich, I would help you
