The answer is solo.
Here’s the breakdown of the clue:
- Zelfredzame is a Dutch word that means “self-sufficient” or “independent.”
- Carpooler is someone who shares rides with others in order to save money and reduce their carbon footprint.
- Putting the two words together, “zelfredzame carpooler” implies someone who carpools by themselves, which is an oxymoron.
- Therefore, the answer must be a word that describes someone who is alone or travels alone, which is solo.
