onta-

verb. beget, create

onta- (pa.t. ónë or ontanë) vb. "beget, create" (ONO, PE17:170)

onta-

verb. to beget, to beget, *conceive (a child); [ᴹQ.] to create

A verb in Tolkien’s writings glossed “beget” and derived from the root √NŌ/ONO (PE17/170; Ety/ONO). In The Etymologies of the 1930s it had a second gloss “create” (Ety/ONO).

Conceptual Development: The Early Qenya Grammar of the 1920s had the word ᴱQ. puita- “beget” (PE14/77), likely based on the early root ᴱ√PU(HU) “generate” (QL/75).

Neo-Quenya: For purposes of Neo-Quenya I’d use this verb primarily with the sense “beget = ✱conceive (a child)”, as opposed to nosta- “to beget = give birth to”. I’d use this verb irrespective of the gender of the parent. When used of non-living or abstract things, it would have the sense “create”: ontanen vinya parma lírion “I begat [= created] a new book of songs”.
