The phrase "Is de reden dat ik niet huw" translates to "Is the reason that I don't marry" in English.
However, it's likely a clue for a crossword puzzle or similar word game because:
* "huw" is an archaic Dutch spelling of "huw" which means "marry"
* The sentence itself is a bit clunky and wouldn't be used in natural conversation.
* The clue mentions there should be a 7 letter answer.
Without more context about the puzzle, it's difficult to give a definitive answer. However, some possibilities for the 7-letter answer based on the clue could be:
* VRIJHEID (freedom)
* ONAFHANGLIJK (independent)
* CARRIÈRE (career)
* REISLUST (wanderlust)
* ANGST (fear)
These are just a few ideas, and the actual answer will depend on the specific puzzle.
