"They write while I sleep."
Translation:Zij schrijven terwijl ik slaap.
Why not terwijl slaap ik? I though the verb was pushed to the end in prepositional phrases
"Tijdens" is preposition (usually translated as 'during'), while "terwijl" is a conjunction. So after "tijdens", you must have a noun, not a subordinate clause. For example:
- Ik zing tijdens het lopen - I sing while walking
Here "lopen" is used as a gerund, something that you'll encounter much later in the tree.
In this sentence you need to use a subordinate clause, because the person writing and the person sleeping are not the same. So it must be "terwijl".
It's just the standard way to conjugate verbs in Dutch. Your question is like asking why it is she sleeps and not she sleep in English.
- ik slaap
- jij/u slaapt
- hij/zij/het slaapt
- wij slapen
- jullie slapen
- zij slapen
