Questions & Answers about Schrijf je adres en postcode duidelijk op de envelop.
Schrijf is the imperative form of schrijven (to write).
In Dutch, the imperative is often just the verb stem:
- schrijven → schrijf
- lopen → loop
- kijken → kijk
So Schrijf je adres en postcode duidelijk op de envelop is a command or instruction: Write your address and postcode clearly on the envelope.
Dutch often uses this bare imperative in instructions, notices, manuals, and forms.
In Dutch, just like in English, commands usually leave out the subject.
Compare:
- English: Write your address clearly.
- Dutch: Schrijf je adres duidelijk.
The subject is understood. In this sentence, it is basically you.
If you want to make it explicit and polite, Dutch often uses u:
- Schrijft u uw adres en postcode duidelijk op de envelop.
So the original sentence is a normal instruction with the subject omitted.
