Learn Dutch: Ben je gisteren verhuisd? - Did you move yesterday?

In Dutch, most verbs use hebben (to have) to form the present perfect tense. However, verbs that describe a change of state or a physical movement from one place to another use zijn (to be). Because verhuizen (to move house) involves a significant change of location, it takes zijn. Literally, the Dutch say "Are you moved?".

The letter 's' is in the 't kofschip rule, so why does verhuisd end with a -d instead of a -t?

To know whether to use a -d or -t, you have to look at the full infinitive verb: verhuizen. When you remove the -en ending, the stem ends in a z (verhuiz). Because z is not in the 't kofschip (or soft ketchup) memory aid, the past participle gets a -d. The z changes to an s for spelling reasons in the final word verhuisd, but the rule always relies on that original z.

Why is verhuisd at the very end of the sentence?

This is the standard word order for the present perfect tense in Dutch. The helper verb (ben) takes the normal verb position right next to the subject (je), and the past participle (verhuisd) gets pushed all the way to the end of the sentence.

The English translation uses the simple past ("Did you move"). Why does Dutch use the present perfect here?
