A neologism for “birth” coined by Helge Fauskanger for his NQNT (NQNT), an abstract noun form of Q. nóna “born”. I prefer to adapt the Early Qenya word nosta.
Quenya
nosta
birth, birthday
nónië
noun. birth

Word Gloss nóna “born”
nosta noun "birth, birthday" (LT1:272; maybe not a valid word in Tolkiens later Quenya because the meaning of the corresponding verb was changed from "give birth" to "beget")
