Questions with prepositions

What do wovon, worüber, wonach and all those mean?
  • They are question words such as woher and warum.
  • Structurally, they are formed using a wo- and a preposition.
But what do they mean?
Don’t focus on the ‘where’ meaning of ‘wo’. In fact, forget for a second that wo means ‘where’ and imagine it's a ‘question word converter’, meaning that it takes a preposition and converts it into a question word.
When do I need those converted question words?
Whenever you want to ask a question using verbs with fixed prepositions like träumen von, suchen nach, diskutieren über. In English, you would rather say what for, what about, ... in German, ...
träumen von
Wovon träumst du?
What do you dream of?
sich freuen über
Worüber freut er sich?
What is he happy about?
These wo-words are only used for questions for which you expect a thing to be the answer, not a person.
- Worüber freust du dich?
- Ich freue mich über den Konzert. - Über wen freust du dich? - Ich freue mich über meine Mutter.
