Learn Dutch: Ik probeer de stilteruimte te reserveren.

When you use the verb proberen (to try) with a second action, you link them using te. It is very similar to the English "to" in "try to reserve". This te is placed right in front of the infinitive verb.

Why does te reserveren go at the very end instead of right after probeer?

In a main clause in Dutch, the conjugated verb (probeer) stays in the second position, but any other verbs (like the infinitive reserveren) are pushed to the end of the clause. The literal word order here is "I try the quiet room to reserve".

Is stilteruimte just one word?

Yes! It is a compound noun combining stilte (silence or quiet) and ruimte (space or room). Dutch frequently glues nouns together into a single word to create new concepts. The article is de because the final part of the compound word (ruimte) is a de word.
