Two Recent English Language Use Changes: Invention and Omission

Since the General Election on June 8, 2017, and the tragedy of the Grenfell Tower Fire, I have been listening to and watching media broadcasts more than usual, and have noticed two significant changes in language use.

One change is limited to a very specific occasion, though it has been growing in popularity over the years.  It is quite consciously deliberate and requires a degree of determination, even courage, on behalf of the speaker.  The other change is usually less obvious, though it too requires a slight degree of determination (if less planning than the other one).  The second one has been around for a lot longer and is growing in popularity (and acceptability).
