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

ôl

noun. forearm; bough

A noun meaning both “forearm” and “bough” in the Gnomish Lexicon of the 1910s (GL/62), related to G. alos “forest” and hence likely derived from the early root ᴱ√ALA “spread” (GL/19; QL/29). The long ô was likely the result of the Gnomish sound change whereby long [[g|[ā] became [ō]]] (GG/14). According to the editors ôl had another gloss “knee” that was deleted.

ôl

noun. height, stature

A word for “height, stature” in the Gnomish Lexicon Slips of the 1910s derived from primitive ᴱ✶alō (PE13/115), appearing after and probably related to G. alw(eg) “lofty” as suggested by the editors (PE13/109). Tolkien specified ôl had no plural.

ôla

masculine name. God of Crafts
