orfalch echor

place name. *High Cleft of the Outer Circle

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.
