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

thorn

noun. eagle

A noun for “eagle” derived from the root ᴹ√THÓRON (Ety/THOR). Its cognates ᴹQ. soron and N. thoron suggest a primitive form ✱✶thoronē, where the middle [o] was lost due to the Ilkorin syncope. Its plural form is not thurin as printed in The Lost Road, but is actually thurnin matching its singular (EtyAC/THOR), as predicted by Helge Fauskanger (AL-Ilkorin/thorn).

dôn

noun. back

A Doriathrin word for “back” explicitly marked as a noun (Ety/NDAN). Its primitive form might have been ✱✶ndān, so that the primitive long [[ilk|[ā] became [ō]]] and the [[ilk|initial nasal [n] was lost before the stop]] (as suggested by Helge Fauskanger, AL-Doriathrin/dôn).

reg

noun. holly

A Doriathrin noun for “holly” attested only in the plural forms regin and region (Ety/ERÉK). It also appeared as an element in the word regorn “holly-tree”. It seems that the latter word replaced reg in the singular, and the original survived only in the plurals, as suggested by Helge Fauskanger (AL-Doriathrin/regorn).
