A word in the Gnomish Lexicon of the 1910s glossed “vale like, of the vale”, an adjectival form of G. enga “plain, vale” (GL/32). It also appeared in the Name-list to The Fall of Gondolin from the same period, where it was described as “that which liveth or dwelleth therein” referring to dwelling in an eng = “plain or vale” (PE15/24).
