wanneer (voegwoord)
Wanneer (When)
Wanneer is a formal alternative to als (when/if). It is used for questions, future events, and repeated habits in the past, but never for one-time past events.
How It Works
In Dutch, choosing the right word for 'when' depends on the timing and frequency of the event. Wanneer and als form a pair that contrasts with toen.
1. Word Order
Wanneer is a subordinating conjunction. This means the conjugated verb moves to the end of the clause. If the wanneer-clause starts the sentence, the main clause uses inversion (Verb-Subject).
2. Usage and Register
- Questions: Wanneer is the only choice for direct and indirect questions (e.g., 'When are you leaving?').
- Future & Habits: Use it for future events or things that happen repeatedly. To emphasize a habit, you can use the phrase telkens wanneer (every time when). Unlike toen, wanneer can be used for the past if the action was a habit (e.g., 'When [every time] I was at my grandma's...').
- Formal vs. Informal: In daily speech, als is the standard. Using wanneer in a casual conversation can sound stiff. However, in writing, wanneer is preferred because als can also mean 'if'.
- Relative Use: In formal writing, wanneer can act as a relative pronoun referring to a time (e.g., 'de dag wanneer...' - the day when...). In these cases, waarop is a very common alternative.
3. The 'Toen' Distinction
The most important rule is that wanneer cannot be used for a specific, one-time event that happened in the past (e.g., 'When I bought my house'). For those single completed actions, you must use toen.
Examples (4)
- Ik weet niet wanneer de les begint.
I don't know when the lesson starts.
Word by Word: I know not when the lesson begins.
This is an indirect question. Notice how the verb 'begint' moves to the end of the clause.
- Wanneer het regent, blijven we binnen.
When it rains, we stay inside.
Word by Word: When it rains, stay we inside.
Because the 'wanneer' clause starts the sentence, the main clause ('blijven we') undergoes inversion.
- Bel me wanneer je tijd hebt.
Call me when you have time.
Word by Word: Call me when you time have.
In this future-oriented statement, 'wanneer' acts as a formal alternative to 'als'.
- Wanneer u klaar bent, kunt u gaan.
When you are finished, you can go.
Word by Word: When you ready are, can you go.
A formal example using the polite pronoun 'u'. The verb 'bent' is at the end of its clause.
Common Mistakes
Using 'wanneer' for a specific past event.
Wanneer ik gisteren in Amsterdam was, zag ik hem.Toen ik gisteren in Amsterdam was, zag ik hem.For specific, one-time events in the past, you must use 'toen'. 'Wanneer' is reserved for the future, habits, or questions.
Incorrect word order in the subordinate clause.
Ik bel je wanneer ik ben klaar.Ik bel je wanneer ik klaar ben.In a subordinate clause, the conjugated verb (ben) must go to the very end.
How It Connects
Learn This First
To use 'wanneer' as a subordinating conjunction, you need to understand that it introduces a dependent clause where the conjugated verb moves to the very end of the phrase. This requires a solid grasp of basic Dutch sentence structure and verb conjugation.
