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).
Ilúvatar masc. name "All-father", God (SD:401, FS, IL; Ilúv-atar, ATA, Iluvatar with a short u, SD:346). Often in combination with the divine name as Eru Ilúvatar, "Eru Allfather", cf. MR:112. "Qenya" genitive Ilúvatáren "of Ilúvatar" in Fíriel's Song, LR:47 and SD:246, the genitive ending is -en instead of -o as in LotR-style Quenya. Cf. the later genitive Ilúvataro in the phrase Híni Ilúvataro (see "Children of Ilúvatar" in the Silmarillion Index)
