An unglossed root in The Etymologies of the 1930s with derivatives like N. gath “cavern” and N. gador “prison, dungeon” (GAT(H)), so probably meaning something like “✱cave”. Its most notable derivative was N. Doriath “Land of the Cave”. But later on in this same entry, Tolkien added Doriathrin words Dor. gad “fence” and Dor. argad “outside the fence”, indicating a conceptual shift in the meaning of this root. Indeed, in later versions of The Silmarillion, S. Doriath was translated “Land of the Fence” containing the element S. iath “fence” (WJ/370, 378), so most likely ᴹ√GAT(H) “✱cave” was abandoned.

An unglossed root in The Etymologies of the 1930s serving as the basis for the name ᴹQ. Fionwe, but the gloss of the element ᴹQ. fion is barely legible, and could be either “haste” or “hawk” according to Christopher Tolkien (Ety/PHI). According to Carl Hostetter and Patrick Wynne, the reading “hawk” is more likely (EtyAC/PHI).
