idk i was tired and i tought it was the funniest thing

I’d actually be down for huitante, in order to keep the latin root like other numbers instead of the greek one

People are actually using huitante and not octante.

Regions use septante, huitante and neunante outside France and especially in Switzerland.

Neunante always struck me as a bit weird (although much better than the math thingy).

Neuvante would seem a more reasonable derivation from neuf.

Would also make it closer to other latin languages like Italian and Spanish.

Ask the guys in Modern times who decided that fick it we will go for the nonsensical method.
