A noun for “a plain” in the Quenya Verbal System (QVS) of the 1940s derived from ᴹ√LAD “lie flat, be flat” with variants landa and lanna (PE22/126), the latter probably derived from ✱ladna with the voiced stop d becoming a nasal before nasal n. It might simply be the noun form of adjective ᴹQ. landa “wide” from The Etymologies of the 1930s (Ety/LAD).
Neo-Quenya: For purposes of Neo-Quenya, I’d stick to the form landa, which appears in an inflected form landannar “to the plains” early in QVS (PE22/125).
