The 6-letter word for “onbuigzaamheid” that fits the description is:
STIJFTE
It means stiffness, rigidity, inflexibility, or stubbornness.
Here are some other 6-letter words that are related to “onbuigzaamheid”, but don’t share the exact root:
- STUGHEID (stubbornness)
- KOPPIGHEID (bullheadedness)
However, none of these words perfectly capture the nuance of “onbuigzaamheid” as it specifically refers to physical stiffness or rigidity.
I hope this helps! Let me know if you have any other questions.
