I wonder why 'threat'? Our language has been continually changing over the centuries, we no longer speak Shakespearian English after all. All languages evolve, responding to the need to express new ideas and describe new experiences. I used to be a terrible purist, growling whenever I heard a cringe-making innovation, but over the years I've come to enjoy these things. As an elderly lady, I've at last realised that 'Nothing stays the same', and that's as it should be.
