Learn Dutch: Vanwege de urgentie stuur ik het papierwerk door. - Due to the urgency, I am forwarding the paperwork.

You would say het door te sturen papierwerk. When creating an attributive modal infinitive from a separable verb like doorsturen, the word te is placed between the prefix (door) and the infinitive (sturen), written as three separate words. This entire phrase then acts as an adjective before the noun.

What is the grammatical difference between using vanwege and omdat to express 'because' here?

Vanwege is a preposition meaning 'due to' or 'because of', so it is followed directly by a noun phrase (de urgentie). Omdat is a conjunction meaning 'because', which requires a full clause with a subject and verb at the end. To use omdat, you would have to say: Omdat het urgent is, stuur ik het papierwerk door.

Could I use wegens instead of vanwege?

Yes, wegens de urgentie is perfectly fine and means the exact same thing. Wegens and vanwege are highly interchangeable when indicating a reason or cause. Wegens can sometimes sound slightly more formal or official in written Dutch, but both are completely natural here.

Can I put a comma after urgentie and say 'Vanwege de urgentie, ik stuur...' like we do in English?
