lómen

adjective. echoing

A Doriathrin adjective for “echoing”, a combination of lóm “echo” and the adjective suffix -en (Ety/LAM). Its Quenya cognate lámina suggests a primitive form ✱✶lāminā, from which the [[ilk|long [ā] became [ō]]] and the -en developed due to Ilkorin a-affection, as suggested by Helge Fauskanger (AL-Doriathrin/lómen).

Conceptual Development: Tolkien first wrote lómin (EtyAC/LAM), perhaps indicating some uncertainty on the exact functioning of Ilkorin a-affection on Tolkien’s part. In the North Sindarin dialect that was in some ways the conceptual successor to Ilkorin, [[norths|final [a] did not mutate preceding vowels]].

lómendor

place name. Lómendor

Ilkorin name of N. Dor-lómen, from which the Noldorin name was derived (Ety/LAM). It is a combination of lómen “echoing” and dôr “land”.

môr

noun. night

A noun for “night” derived from primitive ᴹ✶mǭri (EtyAC/MOR), where the primitive [[ilk|[ǭ] became [ō]]].
