ᴹQ. Arkimbele loc. “Rivendell”
A Quenya name for
Imladris(t) (Rivendell) appearing only in the locative form
Arkimbelesse “at Rivendell” in linguistic notes from the 1940s (PE22/125). The etymology of the name is unclear, but it may be a combination
of
arka “narrow” and
imbe² “dell” as suggested to me by Lokyt in a Discord conversation from 2021-08-25.
