With modern French the interesting one trying to fight this sort of natural evolution by defering a lot of language changes to their Academy and intentionally replacing calques and borrowings with "corrected" versions. Their Academy isn't always successful in getting French speakers to conform to their "corrected" words, but it is fascinating that they still try.
Similar happens in Spanish, I think just the attempt is valuable in and of itself, if for no other purpose that asking the question, "can we do better?". Otherwise one ends with English and its lowest-common denominator antics
