verb. to hollow out, excavate

A verb in The Etymologies of the 1930s appearing in its [Noldorin] infinitive form rosto, glossed “to hollow out, excavate” and derived from the root ᴹ√ROD “cave” (Ety/ROD). Likely its primitive form was ✱rod-tā, where d+t became st in ancient Elvish.

Conceptual Development: The Gnomish Lexicon of the 1910s had G. tumla- {“dig a hole, excavate” >>} “excavate, hollow out” (GL/72), likely derived from the early root ᴱ√TUM(B)U having to do with hollow things, as suggested by Christopher Tolkien (LT1A/Tombo; QL/095).
