Proper Seeker of the Sun Male Syntax

[Empyrean]

Since it's both a defacto rank, in addition to a surname, are the plurals for Tia and Nuhn Tias and Nuhns, or does it get conjugated differently?

[Mishaela]

Since no details are provided I'm going out on a limb here and saying chances are they are words like "deer" which are singular or plural based on context.

Reasoning that may or may not have anything to do with the actual answer:
1) Adding an S to those words just sounds really silly.
2) Japanese words often are singular/plural based purely on context.
3) Only one nunh at a time, why have special grammar for word/situation which would almost never be used?
4) "Nunhs" makes me think of the boardgame Nuns on the Run which is a great game but then I think of mankitties running around in robes trying to steal cakes and bottles of rum without getting caught by the prioress.

Edit: Erps, misread part of naming convention post... could be more than one per tribe at a time.

Well now look at what you've started...

Thank you for the question, Empyrean.

Mishaela is correct here.
The plural for both nunh and tia is the same as the singular form (you will not add an 's').

Example:
My best friend was a tia for 15 years, before becoming a nunh.
Two tia left the tribe today after being defeated in battle by the each of the three nunh.

Also, both nunh and tia are not capped when used outside of names.

Hope that clears things up!
