I have for years known that there was a Dutch bad word "stront" meaning "shit" but I expected it was spelled "stroent" until I looked it up just now.
I have also known the Italian bad word "stronzo" which has many uses but literally also means "shit".
Only in the last half hour or so did I consider the similarity and wonder if they could be related. I haven't been able to find any discussion of this or an etymology for the Dutch word, but apparently the Italian word comes from Lombard.
Do we know if and how these words from a pair of countries without a border might be related?
