## Etymology
From Middle English clough, clow, cloȝ, from Old English *clōh, from Proto-Germanic *klanhaz, *klanhō (“cleft, sluice, abyss”), of uncertain origin, possibly ultimately from Proto-Indo-European *gel- (“to form into a ball”).
Cognate with Scots cleuch (“gorge; ravine”), Old High German klāh (in placenames), Old High German klingo, klinga (“brook, cataract, gulf, rapids”). Perhaps conflated or influenced by Old Norse klofi (“a cleft or rift in a hill, ravine”); compare Dutch kloof (“a slit, crevice, chink”). See also cling, clove.
