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.
gwene
adjective. green
gwene
root. *large, wide
A root in the Gnomish Lexicon of the 1910s, with the derivatives like G. gwen(n) “big, large; fine” and G. Bladorwen “Wide Earth, Mother Earth” (GL/23, 45), thus probably meaning “✱large, wide”. The name Bladorwen did not survive in the legendarium and there are no signs of this root in Tolkien’s later writing.

wenya
green, yellow-green, fresh
wenya adj. "green, yellow-green, fresh" (GWEN), apparently "fair, beautiful" ("probably originally "fresh, fair, unblemished especially of beauty of youth") in a later deleted note (PE17:191).
An adjective for “green” derived from the root ᴹ√GWEN (Ety/GWEN). Its Quenya cognate ᴹQ. wenya suggests its primitive form was ✱✶gwenyā [gwenjā]. If so, it is an example of how, after [[ilk|final [a] was lost]], the [[ilk|final [j] became [i]]] and then became [e], as suggested by Helge Fauskanger (AL-Ilkorin/gwene).
