Learn Dutch: Deze luxe is geweldig, want we hoeven 's avonds niets te doen. - This luxury is great, because we don't have to do anything in the evening.

Yes! The verb hoeven (to need) is always used with a negative word. Usually that is niet (not), but it works perfectly with niets (nothing) or niemand (nobody) too. Together, hoeven ... niets te doen means 'don't have to do anything'.

Why is the word order normal after want instead of pushing the verbs to the end?

The word want (because) connects two normal sentences without changing the word order. If you used the other Dutch word for because, omdat, the verbs would move to the end: omdat we 's avonds niets hoeven te doen.

What exactly does the 's in 's avonds mean?

It is a leftover from old Dutch, standing for des (of the). Today, 's avonds is a fixed expression meaning 'in the evening' or 'evenings'. You will also see this pattern in 's morgens (in the morning) and 's middags (in the afternoon).

Why does te doen go at the very end of the sentence?
