meneg

cardinal. thousand, thousand, *a large number

A word for a “thousand” implied by the name Menegroth “Thousand Caves” (S/56; WJ/415). It is possible this word simply means “✱a large number” rather than being precisely 1000.

Conceptual Development: In the 1930s, the name Menegroth was Ilkorin (Ety/ROD), and thus the word meneg likely also belonged to that language. The Gnomish Lexicon of the 1910s had G. moth(in) or mothwen “thousand”, originally meaning “flock” and related to G. moth “sheep” (GL/58).
