>>126870I don't know much about you but I think you guys invented alphabet because you preserved it on the level of like 3 vowels. And those vowels are of the common sequence between kana and alphabet aiu (kana goes aiu-eo, and in alphabet they stuck those e & o in between)
So you whether invented it or preserved it on the very early stage. Grand Respect.
I also think the word kana could be coming from your abakada word. But I might be wrong on this one, though I think I'm not.
