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

orn

noun. tree

A Doriathrin noun for “tree” derived from the root ᴹ√ÓR-NI or ᴹ√ÓRON (Ety/ÓR-NI, EtyAC/NEL). According Tolkien, it was “in Doriath used especially of beech, but as a suffix [it was] used of any tree of any size” (Ety/ÓR-NI). The root ᴹ√ÓR-NI in The Etymologies suggests a primitive form of ᴹ✶ornĭ, but elsewhere Tolkien indicated the primitive form was ᴹ✶ornē (e.g. on SD/302). Both primitive forms would have produced Ilk. orn, as noted by Helge Fauskanger (AL-Doriathrin/orn).

tund

adjective. tall

An adjective for “tall” derived from primitive ᴹ✶tundā (Ety/TUN). It is an example of how the Ilkorin a-affection was prevented or reverted before [nd], as suggested by Helge Fauskanger (AL-Ilkorin/tund).

gald

noun. tree

A Doriathrin noun for “tree” derived from the root ᴹ√GÁLAD (Ety/GALAD), probably from a primitive form ✱✶galadā with the second a lost due to the Ilkorin Syncope. Note that the first element [[ilk|[gal-] did not reduce to [gl-]]] because the initial syllable was stressed in the primitive word.
