French of course also have many original grammatical torture instruments. You might think that as a bastard child between Latin and the Germanic Frank tribe dialects it’s no wonder, though elimination of noun declension is rather surprising from this perspective. The truth is that all languages out there have their own dungeon with many traps and treacheries included.
