My comment on the dragon language thing is more of a question of how the fuck the dragons are supposed to speak some of the sounds. For example, just try making a V sound without using your lips. B, F, M, P, V, and W are all impossible to form without lips. Dovahkiin is impossible to say because of that.
There's at least three answers to that. Two have been given: Non-human physiology and magic.
The third is the fun one: There's no reason whatsoever to assume that the
dragon 'V' sound sounds anything at all like the
human 'V' sound. There's a number of real-world languages that use (or can use, anyway) the same symbol ("letter") to designate different sounds than the symbol is used to designate in other languages. My own fun idea is that the draconic V is the sound of their upper teeth crunching through the bones of overly curious humans
I could totally see any length conversation between dragons requiring an small orgy of humanoid consumption.
Towns are depopulated. This is why dragons randomly attack things, obviously. They're just looking to have some quality conversation with someone.
Also, "dragons" in TES are actually wyverns, with no front legs or claws.
Human tells giant flying lizard with non-standard anatomy that they can't call themselves 'dragon', 'cause 'dragons' have six limbs.
Giant flying,
carnivorous, lizard calmly reminds tiny, noisy,
edible monkey that these sort of arguments are why they, the
dragons, invented ketchup.
Crunchy chatterbox withdraws complaint shortly thereafter, one way or another.
Moral of the story: That which is considerably bigger than you and capable of speech can call themselves anything they bloody well please. Whatchu gon' do about it?
