Learn Dutch: U dient de wettelijke regels te respecteren. - You are obliged to respect the statutory rules.

Dienen te + infinitive is a highly formal way to say 'must' or 'are obliged to.' While U moet de regels respecteren is perfectly correct and common in speech, dienen te is typically used in official written instructions, legal texts, or formal announcements to sound objective and authoritative.

Could I use jij instead of u and say Jij dient de wettelijke regels te respecteren?

Grammatically, yes (jij dient), but in practice, you will almost never see this. Because dienen te is such a formal structure, it is almost exclusively paired with the formal pronoun u. Using the informal jij with this official vocabulary sounds awkwardly mismatched.

Why is te respecteren placed at the very end of the sentence?

Dienen acts similarly to a modal verb here, pushing the main action verb (respecteren) to the end of the clause. When a verb requires te before the infinitive (like dienen, proberen, or hoeven), the te stays attached directly in front of that final infinitive.

How is the adjective wettelijke formed, and why does it get an -e at the end?
