A boulder is a stone rounded by erosion and moved from its original position.
Something like this:
This is an glacial erratic boulder (which doesn't imply that it's unreliable, but that it's been moved by a glacier). Photo by Donald Perkins of a memorial to the Geologist Sir Andrew Crombie Ramsey at Eglwys Sadwrn Sant, Wales
It has to be more than 256 mm across or else it's a cobble.
The real reason for featuring this word on The Word Den, however, is its derivation.
So, without further ado:
Word To Use Today: boulder. This word comes from the Old Swedish bulder, which means rumbling.
