Eh. It's not a deterioration, it's just language. It's not like there was a carefully designed "one true language" in the past and this is a fallen world speaking only inferior pidgins. Even in the bible, we can see Jesus starting a lot of stories with "truly, truly I say unto you..." followed by a parable.
