Like every other place name in the British Isles, Inner and Outer Qwghlm represent a gross misnomer with ancient and probably comical origins. Inner Qwghlm is hardly even an island; it is joined to the mainland by a sandbar that used to come and go with the tides, but that has been beefed up with a causeway that carries a road and the railway line. Outer Qwghlm is twenty miles away.
