I've started learning German only recently and as far as I know Wie is how in English and Was is what. However, I have noticed that sometimes it says Wie where it would be more logical to say Was. For example, in my book it says "Wie ist deine Adresse?" Can anyone explain what types of questions use Wie and what types use Was? And are there any cases where the two can be used interchangeably?
Thanks a lot!
