Minor correction:

> The Old Norse Ö in 'dögum' was pronounced just like the regular A

in the other cases of the same word - only it was nasalized ( = short
nasal A). The pronounciation Ö (and spelling) are later."

Now I see where the confusion was coming from. Instead of 'nasalized'
what I meant to say was that the A was pronounced "in the direction"
of O. The short of this sound heard in 'daogum' is not nasalized - I
hope this clears up the confusion. Please see the vowel-sets shown in
my 3rd post about the 'vowel-system' for more information.
