Wie is dein Vorname/Nachname? OR Was...? Hi, I have to fill in either WIE or WAS in the questions in the subject box above: ---- ist dein Vorname? --- ist dein Nachname? (I assume it is better to use Heißen in general --- here, however, I am forced to use this construction). Are both options (Wie, Was) possible/ idiomatic/equally common? Thanks for your help.
