A noun appearing as G. {tentha >>} tent “toe” in the Gnomish Lexicon of the 1910s (GL/70). Given the related verb tentha- glossed “feel with the feet, walk on tiptoe”, it was probably based on the early root ᴱ√TENE “touch, feel” (QL/91).
Neo-Sindarin: I would retain ᴺS. tent “toe” for purposes of Neo-Sindarin, reconceived as a derivative of √TEN “point (towards)”.
