A word for “child” appearing in various late notes and phrases (NM/31; PM/391; VT49/42), derived from the root √NŌ/ONO “beget, be born” and once appearing in a variant form onwe (PE17/170). Giving its derivation, its actual meaning may be closer to “✱offspring”, as first suggested to me by Tamas Ferencz.
Conceptual Development: In The Etymologies of the 1930s, ᴹQ. onna was instead glossed “creature”, though it was still derived from the root ᴹ√ONO “beget” (Ety/ONO).
indi pl. noun, apparently a name of Men, hardly valid in Tolkien's later Quenya (LT2:343). Compare, however, the final element of Valarindi "Offspring of the Valar", suggesting that #indi can be used for "offspring" (the Quenya word is apparently plural). It may be that in Valarindi, a h has dropped out following r, and that the independent word would be *hindi (as a variant of -hín, -híni "children").
