This discussion is really offtopic as it has nothing to do with Minecraft.
But personally I have nothing against language evolving, but cant stand it being miss used and abused. And I think there is nothing wrong with trying to preserve what we have while adding to it.
A great example of it is the Danish saying: "Bjørne tjeneste". Translates directly into "Bears favour". It originally means doing someone a favour(probably from good intentions) but ultimately causing them harm. But because because a portion of people are ignorant and thought it was doing someone a good favour, it is now registered in the dictionary as both!.... /facepalm
So now the saying is IMO ruined because any time you want to use it, you also have to spend time explaining which of the two opposite meaning version you actually mean.
