What are Extended Question Words?
Extended question words combine a preposition with 'wer' (who) or 'was' (what) to ask about things, actions and reasons in German. Instead of saying a preposition + was separately, you use a single word like 'wofür' or 'womit'.
Extended question words (wofür, womit, worüber, etc.) combine a preposition + wer or was into one word for asking 'with what', 'about what', 'why' and similar questions.
