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'.

Short answer

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.

FAQ

What are extended question words in German?

Single words that combine a preposition with was to ask questions — e.g. wofür (for what), womit (with what).

How do you form extended question words?

Use wo- + the preposition sound: wofür, womit, worüber, wovon, wozu, woran, etc.

When do you use extended vs. separate forms?

Extended forms (wofür) for things; separate (mit wem) for people.

What about wer — can you use wo- + wer?

Rarely. For 'whom' you say 'mit wem' separately, not 'wowem'.
