I tend to get Simarillion brain-freeze if things have multiple names. "This town is known as Khiz-Koran amongst the dwarves, Santoregnia by the people of the mountain and Little Buttwhistle amongst the halflings.."

Right? That’s part of the difficulty. But, see also, Falklands/Malvinas, English Channel/British Sea, Bristol/Place by the Bridge, Persian Gulf/Arabian Gulf/Bitter Sea, Rio Grande/Bravo, etc.
