A noun in the Gnomish Lexicon of the 1910s glossed “earth, soil” (GL/42). Its derivation is unclear, but it might be from a strengthened form of the root ᴱ√ROTO “hollow”.
The word G. dorven “landscape, scene” appeared in the Gnomish Lexicon (GL/30), probably a combination of G. dôr “land”G. benn “shape”.
Neo-Sindarin: For purposes of Neo-Sindarin, I would adapt this word as ᴺS. dorgant “landscape, scene”, a combination of S. dôr and later word S. cant “shape”, also hinted at by the word S. dorgannas“shapes of the lands” = “✱geography”.
