There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.
Below: Tolkien's Late Period (1950–1973). These are from Tolkien's late conceptual period — his most settled forms of the languages. Prefer these over the earlier ones above when composing new text.
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)”.
