An “old short allative” form appear in the Declension of Nouns from the early 1930s with suffixal -r, with both monosyllabic mar and longer mardar (PE21/25, 27). Tolkien said the longer for mardar was “less usual” (PE21/27), but it is more distinct from már “home”. This allative variant is probably related to ᴹQ. tar “thither” < ᴹ✶tad from later in the 1930s (Ety/TA; PE19/52).

ilu vanya, fanya, eari, i-mar, ar ilqa ímen

hún
noun. earth, earth, *ground
A word in the Declension of Nouns from the early 1930s with stem form hun- and gloss “earth” (QL/39). It might be a later iteration of ᴱQ. han “ground, earth” from the Qenya Lexicon of the 1910s (QL/39), and if so then hún might also be used as “✱ground”. I think it is useful to assume so for purposes of Neo-Quenya, as the other attested word for “ground”, Q. talan, is probably used more often for “floor”, including floors above the ground level.
má Archaic
noun. land, region
The “veins of the world” in some cosmological notes from the 1930s (SM/241-2, 255), also appearing in The Etymologies as combination of mar “world” and the plural of talma “root” (Ety/TAL).
