* regnoun. 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).
