The Dutch word "monster" means "specimen" in English. This is actually of Latin origin, and plenty of English words come from the same latin root (monstrum) like "demonstrate".

Likely as not, though, the surname "Monster" just reflects a family origin in the Dutch town of Monster, near the coast southwest of The Hague.

Thanks for correcting me. Apparently, I was too quick to accept the first translation proposed by https://translate.google.com/?sl=en&tl=nl&text=monster&op=tr...

And thanks to your Latin lesson, now I know that monster in English means specimen too! (I prefer to understand words in terms of their roots.)
