ᴹ√(E)REK root. “thorn, holly”
The root ᴹ√EREK appeared in The Etymologies of the 1930s with the gloss “thorn” and derivatives of 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 indicate the continued validity of these roots.
