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

ham

noun. ground, level of Earth’s service [surface]

A noun in the Gnomish Lexicon of the 1910s glossed “ground, level of Earth’s service” (GL/48); the editors suggested that “service” is almost certainly a slip for “surface”. It is clearly a cognate of ᴱQ. han (ham-) “ground, earth”, and so must be derived from the same root ᴱ√HAMA (QL/39).

hacha

noun. the hams, buttocks

A word appearing as G. hacha “the hams, buttocks” in the Gnomish Lexicon of the 1910s, with a Qenya cognate ᴱQ. hakka (GL/47).

Neo-Sindarin: For purposes of Neo-Sindarin, I would adapt this word as ᴺS. hach from a Neo-Root ᴺ√KHAK “squat”.

noun. judge
