Hanian does not have gendered nouns, rather they are classified nouns. What form of the is used for them depends on what the word is and how it might be modified. Using the in Hanian and classifications in regards to words is the same thing. This is kind of hard to explain as it’s so different. There are five different ways of doing this and each of them is used with a different set of words. For nouns ar, az, od and do is used. For nouns with adjectives in the sentence cluster and bi and vef is used. In case of the last one, it’s a bit tricky as it’s attached to the noun. binoun vef adjective.
Hopefully I didn’t loose any readers to confusion yet.
ar is used primarily for things, resources, machines, stuff, insults and things that can’t be classified appropriately.
az is used for holy things, energetic things, time, emotions (positive or neutral ones) and abstract things.
od is used for creatures, natural things, weather, slaves, food, places, negative emotions, body parts and the like.
do is used for people, groups, systems, governments, professions, symbols and so forth.
bi is used for any noun with adjective(s); never for adjectives alone & vef them too!
So just to give a few examples.
the day – would use az – because it’s time based.
the waterfall – would use od – because it’s something natural.
the wise one – would use bi – because it’s preceded by an adjective, it is attached.
the Richter scale – would use do – because it’s a system. (tricky, I know)
the jealousy – would use od – because it’s a negative emotion.
the yellow sun – would use bi – because it’s preceded by an adjective, it is attached.
the stars and stripes – would use do – because it’s a symbol (of a government no less)
the ghost – would use az – because it’s an energetic thing.
the star ship – would use ar – because it’s a technological machine.
Saying it’s yellow, would not receive any of these, as there is no noun there.
Hopefully this helps a little in the strangeness that’s Hanian. Some will be tricky, so if you don’t know the right one, simply use the one closest to it or ar if you really have no earthly idea what you’re doing.
