Elements
Word Gloss or “above, above; [G.] onto, on top, on” falch “*cleft, ravine, [ᴱN.] cleft, ravine” echor “outer circle; encircling”
Orfalch Echor
noun. encircling, up-going valley
A ravine in the Echoriath leading to Gondolin (S/239). This name seems to be a combination of [N.] or “above”, falch “cleft” and echor “outer circle”, perhaps meaning “✱High Cleft of the Outer Circle”.
Conceptual Development: In the earliest Lost Tales, a similar ravine was named G. Glorfalc “Golden Cleft” (LT2/150), whose the final element G. falc “cleft” resembles the element in the later name, possibly of the same meaning.
