The clue “Siert een domkop (crypt.)” translates to “Adorns a fool” in Dutch. It’s a wordplay hinting that the answer might be something someone might put on (adorns) despite not being particularly intelligent (domkop translates to fool).
Looking at the letter count (11 letters), the answer is HALSKETTING. This Dutch word means “necklace,” which makes sense in the context of the clue. While a necklace can be a beautiful adornment, it doesn’t necessarily require any intelligence to wear, which adds a touch of humor to the wordplay.
