A Doriathrin noun meaning “realm” derived from the root ᴹ√ƷAR or possibly ᴹ√GAR (Ety/ƷAR), perhaps from a primitive form ✶ɣarda or ✶garda given its cognates ᴹQ. arda and N. ardh. Likely the [d] became [ð] after [r] and then the final [ð] became [θ], a derivation that is supported by the (rejected) earlier entry Dor. garth (dh) in the Etymologies (EtyAC/ƷARA). These probable developments were noted by Helge Fauskanger (AL-Doriathrin/garth).
regionplace name. Hollin
A Doriathrin noun for “land” (EtyAC/NDOR) apparently from primitive ᴹ✶ndorē (Ety/NDOR). If its primitive form indeed had a short [o], then this word may be an example of how short vowels sometimes lengthened in monosyllables in Ilkorin.
* 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).
