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.

(e)rek

root. thorn, holly

The root ᴹ√EREK appeared in The Etymologies of the 1930s with the gloss “thorn” and derivatives meaning “prick” or “holly” in both Quenya and Noldorin (Ety/ERÉK). Elsewhere in the document it appeared in its unaugmented form ᴹ√REK (EtyAC/REK). It was the basis of the two names Ilk. Region and N. Eregion “Hollin”. The continued appearance of these names in the legendarium indicates the continued validity of these roots.
