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.

belin

adjective. expanded, unrolled, unfurled, set (of sails)

An adjective appearing in the Gnomish Lexicon of the 1910s as G. {belum >>} belin “expanded, unrolled, unfurled, set (of sails)”, based on the verb G. belu- “unroll, unfurl” (GL/22).

Neo-Sindarin: Since I retain the Neo-Root ᴺ√BELU “unroll, ✱unfurl” to serve as the basis for “sail” words, I would retain and adapt this Gnomish adjective as ᴺS. belen “expanded, unrolled, unfurled, set (of sails)”.

eilin

noun. pool

fenlug

noun. snake

fent

noun. snake

A word for “snake” in the Gnomish Lexicon of the 1910s, along with a deleted variant fenlug (fenlog-) (GL/34), the latter probably a combination with G. lûg “snake”. It was clearly a cognate of ᴱQ. fent “serpent” from the contemporaneous Qenya Lexicon (QL/38).

gwerb(e)lin

noun. top, whirligig, *(lit.) wind-unwind

A noun for a “top, whirligig” in the Gnomish Lexicon of the 1910s, apparently a combination of G. gwer- “turn” and [possibly] G. belin “unrolled” (GL/22, 46), so perhaps meaning “✱unrolled turner”.

nîn Archaic

noun. pool

An archaic noun in the Gnomish Lexicon of the 1910s glossed “pool” (GL/60), almost certainly derived from the early root ᴱ√NENE (QL/65).
