I was studying some Ancient Greek, and found out that the declination of some irregular nouns are very similar.
I started wondering if there is actually a language that is mother of Altaic languages and Indo-European languages that we can partially reconstruct by finding other languages that have this feature, or these are just some borrowed words as a result of some peculiar ancient migration.
Is there another Indo-European language that has this "-den", "-de" postfixes for declensions of nouns?
Ev-den (from house)
Ev-de (in house)
οἴκο-θεν (from house)
οἴκα-δε (towards house)
