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

nel

noun. point, end, tip, jutting end

A word in the Gnomish Lexicon of the 1910s glossed “point, end, tip, jutting end” (GL/60), clearly based on the early root ᴱ√NELE “point” (QL/65).

egli(n)

noun. needle

A noun in the Gnomish Lexicon of the 1910s appearing as G. eglin or egli “needle” based on G. eg “point” (GL/32).

Neo-Sindarin: The root √EK “sharp point” survived in Tolkien’s later writings (WJ/365), so I’d retain ᴺS. eglin “needle” for purposes of Neo-Sindarin.
