onna
creature
onna noun "creature" (ONO), "child" (PE17:170), also translated "child" in the plural compound Aulëonnar "Children of Aulë", a name of the Dwarves (PM:391), and apparently also used = "child" in the untranslated sentence nai amanya onnalya ter coivierya ("k") "be it that your child [will be] blessed thoughout his/her life" (VT49:41). The form onya (q.v.), used as a vocative "my child", is perhaps shortened from *onnanya.
