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.

An untranslated word appearing in notes on The Feanorian Alphabet from the late 1940s or early 1950s (PE23/26). It might be a later iteration of G. adhwen “approach, avenue” from the 1910s, or is perhaps related to S. adu and ᴹQ. atwa “double”.
