ᴹQ. onóne n. “kinswoman; sister” (Category: Relative)
A word glossed “sister” under the root ᴹ√NŌ (Ety/NŌ), but in the entry for ᴹ√THEL Tolkien said it was “usually used of blood-kin” and its cognate was ON. wanūre “kinswoman”, which seems like a better translation. It is simply the root ᴹ√NŌ “beget” with the prefix ᴹQ. o- “together” and a feminine suffix.
