(i onna, in onnar), also prefixed edonna- (i edonna, in edonnar), passive participle ?edonnen.
A verb implied by the adjective (passive participle?) onnen “born” as in Abonnen “After-born” (WJ/387). It also appeared as an element in N. ed-onna “beget” in The Etymologies of the 1930s under the root ᴹ√ONO “beget”, but it is not clear whether it could function as an independent verb in this period (Ety/ONO).
Neo-Sindarin: For purposes of Neo-Sindarin, I would use this verb to refer primarily to the actions of the mother = “✱to birth, give birth to”, and would reserve edonna- “to beget” for actions of the father.
