Learn Dutch: Blijf je lid, dan krijg je korting. - If you stay a member, then you get a discount.

This is a verb-first conditional clause. In Dutch, you can drop the word als (if) to make a conditional sentence. When you do this, the verb moves to the very first position. So Blijf je lid translates to 'If you stay a member.'

Can I still use als to say this?

Yes, you can! If you use als, the first part becomes a standard subclause where the verb moves to the end. It would be Als je lid blijft, dan krijg je korting. The meaning is exactly the same, but the verb-first version is very common and sounds a bit more direct.

Why does the second part say dan krijg je instead of dan je krijgt?

In Dutch, the main verb is almost always the second piece of information in a main clause. The word dan (then) takes up the first position in that clause, which pushes the verb krijg right in front of the subject je. This swapping of subject and verb is called inversion.

Is the word dan required in sentences like this?

When you drop als and start with a verb, it is very common and strongly recommended to start the second half with dan. It acts as a bridge that makes the 'if..., then...' relationship perfectly clear to the listener.

Is the word lid used for any kind of membership?
