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.

Doriathrin

-il Reconstructed

suffix. feminine suffix

Apparently a feminine suffix attested in the name Thuringwethil “(Woman of) Secret Shadow” (Ety/THUR) and the noun tóril “queen” (Ety/TĀ).

gangel

noun. harp

A noun meaning “harp” derived from the root ᴹ√ÑGAN(AD) (Ety/ÑGAN), probably from a primitive form ✱✶ngandellē based on its Quenya cognate ᴹQ. nandelle. Its plural form genglin is a good representation of the rules for plural nouns in Ilkorin: the suffix -in, the syncope of the final vowel and mutation of other vowels. It is also an example of how primitive [[ilk|[nd] sometimes became [ŋg]]] in Ilkorin. As suggested by Helge Fauskanger, this may be due to assimilation to the preceding [g] (AL-Ilkorin/gangel).
