Male Viera names?

[Fenral]

This line, actually:

Nunh status does not equate to leadership within a tribe, and in fact, very few nunh ever become leaders.

"Matriarchal" was bad word choice on my part, but it does seem to indicate women are generally the leaders. The distinction between "breeding male" and "leader" isn't present in later texts, and the Encyclopaedia asserts they're the same:

The Seekers of the Sun are a highly patriarchal culture, with each tribe centered around a strong breeding male (nunh), whose duty it is to form a harem and lead his people to glory and prosperity.

Chronologically, the Naming Conventions posts are the "oldest," dating to the beta phase of ARR. Then 2.0 released and we got Forgotten Springs where that was clearly not the case, and then with Stormblood we got the Peering Stones, the Encyclopaedia, and most recently Alphi's euphemistic explanation delivered via Y'shtola. At some point the devs decided to just make them lions (minus the infanticide). Though with lions, it is also true that the females do most of the day-to-day work, so it may be an allusion to that.
