Sad, very sad, breaking the fun.
Or would "etymology" be related to "nomenclature"?
But also, ha, why is it written boulder in the nomenclature? Could it be of a Dutch origin?
How would that be possible?
I couldn't have imagined it.
Now, a short moment of truth:
I didn't see anything wrong in "boulder" because of its consonance with "bolder", and that in English, bollard is the same as in French.
So, it is Terry's question that made me think about the meaning of boulder, and why it seemed so strange for English speaking people in its meaning of bollard. What was the link between the Boulder Dam and some lost Poller in Hamburg? None at all, unless boulder came from bolder!
Voilà .
