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.

Gnomish

(g)leg

adjective. keen, sharp, piercing

Gnomish [GL/39; GL/53; GL/61; LT1A/Tári-Laisi; QL/050] Group: Eldamo. Published by

bactha

noun. leg

A noun in the Gnomish Lexicon of the 1910s for “a leg” (GL/21), clearly with a different etymology than ᴱQ. pelko “leg” (QL/73), probably derived instead from the early root ᴱ√VAHA “travel” (QL/99).

dramborleg

proper name. Thudder-sharp

The axe of Tuor, translated “Thudder-sharp”, appearing in various early name lists along with its shorter form Drambor (LT2/203; PE13/103; PE15/22). This name seems to be a combination of drambor “thudder” and leg “sharp”, as suggested by Christopher Tolkien (LT2A/Dramborleg; LT1A/Tári-Laisi). Its Elvish name did not appear in later works (UT/172).

thrimp

noun. stalk

A noun appearing as G. thrimp “a stalk” in the Gnomish Lexicon of the 1910s (GL/73), clearly based on the early root ᴱ√SIRIP (QL/84).

Neo-Sindarin: I retain ᴺS. thrimp “stalk” for purposes of Neo-Sindarin, based on an updated Neo-Root ᴺ√THIRIP to better fit Sindarin phonology.

thripthon

noun. stem

A noun for “stem” in the Gnomish Lexicon of the 1910s (GL/73), clearly based on the early root ᴱ√SIRIP (QL/84). It had a dialectical variant G. fripthon, but that word was glossed “stalk” (GL/36).
