Word Origin and History for tor
n.

"high, rocky hill," Old English torr "tower, rock." Obviously cognate with Gaelic torr "lofty hill, mound," Old Welsh twrr "heap, pile;" and probably ultimately from Latin turris "high structure" see tower (n.)). But sources disagree on whether the Celts borrowed it from the Anglo-Saxons or the other way round.
