Hrothgar is an Old English name, most famous for being the name of the king in the tale of Beowulf. However the name itself is a combination of the old English words 'Hroth' and 'Gar' which translate to 'Glory' and 'Spear'.
So the mountain's name (High Hrothgar) literally translates to High Spear of Glory. More than anything for me remembering this factoid has set the tone for skyrim better than anything I've read yet. Hope it works for you guys too.
Edit: Also bearing this in mind have we heard anything about spears making a possible come back in Skyrim yet?
