The name Drumclog may have Brittonic origins.[1] The first part of the name may be *drum, meaning "a back, a ridge",[1] and the second *clog, "a rock, a crag, a steep cliff" (Welsh drum-clog),[1] in place names meaning a standing stone or other stones of perceived significance.[1] The second part of the name could also be the cognate Gaelic element clach.[1]
