A Doriathrin noun meaning “holly-tree”, a combination of (archaic?) reg “holly” and orn “tree” (Ety/ERÉK, ÓR-NI).
Doriathrin
reg
noun. holly
regorn
noun. holly-tree
regornion
place name. Hollin
region
place name. *Hollin
dôr
noun. land
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.
garth
noun. realm
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 [[ilk|[d] became [ð] after [r]]] and then the [[ilk|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).
lindon
place name. Musical Land
mâb
noun. hand
An Ilkorin and Doriathrin noun for “hand” derived from primitive ᴹ✶mapā (Ety/MAP, EtyAC/MAP), where the [[ilk|voiceless stop [p] voiced to [b] after the vowel]]. Since its primitive form had a short [a] and its Ilkorin form a long [ā] (EtyAC/MAP), this word is an example of how short vowels sometimes lengthened in monosyllables in Ilkorin.
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).
