ᴱN. barth n. “world, earth” (Category: World)
An Early Noldorin word from the 1920s glossed “world” in the Early Noldorin Grammar (PE13/120) and “earth” Early Noldorin Wordlists of the 1920s (PE13/138). Its mutations in the Early Noldorin Grammar make it clear anciently began with mb-, so it was probably derived from the early root ᴱ√MBARA “dwell, live” (QL/63).

A word in the Gnomish Lexicon of the 1910s glossed “Earth, ground, soil”, apparently derived from the root ᴱ√mar- (GL/56). Tolkien also had G. Môr “the Earth”, so perhaps mar mainly meant “earth” in the more ordinary senses. For purposes of Neo-Eldarin, I’d use later S. ceven for “earth”.
