In the course of skyrim, we come to understand the basic structure of the dragon tongue and the dragons' names. Alduin is Al-Du-In, Destroyer-Devour-Master; Paarthurnax is Paar-Thur-Nax, Ambition-Overlord-Cruelty, (yikes.) Their names are shouts, triadic in nature.
I was noodling on this while booting up Skyrim to see what else I could find in game texts (because damn is this game a treasure-trove for lore) when Morihaus popped back into my head, specifically the title Breath-of-Kyne. Breath-of-Kyne: Su'un-Do-Kaan.
Was the demigod 'winged bull' a dragon? Su'undokaan.
I was wondering if any of the older lore-buffs would be willing to weigh in on this, if you find it plausible, etc; it's fairly speculative, but it's been gnawing at me.
