A word in the Declension of Nouns from the early 1930s glossed “dust”, given as an example of declensions for nouns that in ancient times ended with short -ŭ: mulǔ- (PE21/10-11). It is probably a later iteration of ᴱQ. mul (muld-) “fine powder” from the Qenya Lexicon of the 1910s, a derivative of the early root ᴱ√MULU “grind (fine)” (QL/63). In notes from the late 1950s or early 1960s, Tolkien gave Q. mulë for “meal” = “✱coarsely ground flour”, so it seems ✱√MUL “grind” either survived or was restored. For purposes of Neo-Eldarin, I think it is appropriate to use this word with the earlier sense “fine powder” as well.

mulo
noun. dust, dust, [ᴱQ.] fine powder
nangwa
noun. jaw
A noun for “jaw” The Etymologies of the 1930s derived from primitive ᴹ✶nakma under the root ᴹ√NAK “bite” (Ety/NAK). It was possibly displaced by anca “jaw, jaws”, which was also introduced in The Etymologies of the 1930s, but continued to appear in later documents included The Lord of the Rings Appendix E (LotR/1123). However, it might be that nangwa refers to a single “jaw” (upper or lower), while anca refers collectively to both “jaws”.
pé
noun. mouth
A noun in The Etymologies of the 1930s glossed “dust” derived from the root ᴹ√ÁS-AT (Ety/ÁS-AT). It was also mentioned in The Feanorian Alphabet from the late 1930s with the same form and meaning (PE22/21-22), and in the revisions of that document from the 1940s, though there it was replaced with ᴹQ. osto as a name for one of the tengwar (PE22/50). This replacement may only have to do with tengwar names, and doesn’t necessarily invalidate asto “dust”.
