Peter T. -- Those are very interesting points you've brought up. I believe that many of the "new" words are mere inventions by television/radio presenters and/or writers who are looking for a verbal 'hook' for their stories. This words or phrases are meant to add punch to their (to use another grossly overused phrase) "soundbytes".

And to name another word that sends shivers up my spine -- facilitate -- May all the body parts of all users of that little gem become and remain 'facile' . . .
