A noun in The Etymologies of the 1930s glossed “cave”, apparently a combination of N. gath “cavern” and ᴹ√ROT “tunnel” (Ety/GAT(H)). Its initial element also appeared in the name N. Doriath “Land of the Cave”, but in later writings S. Doriath was redefined as “Land of the Fence” with final element S. iath “fence” (WJ/370), so N. gathrod “cave” was probably abandoned.

A deleted word in The Etymologies of the 1930s, the only derivative of the deleted root ᴹ√PHELEK “(animal’s) horn; steep mountain peak” and thus probably of similar meaning (EtyAC/PHELÉK). In later writings, S. feleg was a word for “cave”.
