Hi there,
The icelandic suffixed definite article, is enigma to most of us.
The the oldest book I have read that my ancestors compare it to "este"
in Latin. In the way that the noun suffixed marks subset.
In genaral suffixed noun can be understood as a subject.
Often subject under the corresponding not suffixed noun.
The genitive in general demands the suffixed article.
Maybe this explains something.
