I often notice when people are using a word in different ways. In the comic book field, some use the word "hack" to denote a writer or artist who turns in shoddy work, knocked-out as fast as possible, just to get a paycheck. And some use it to denote a writer or artist who reliably turns out decent work at an amazing volume. Those are not the same thing and sometimes, I read a piece where someone says "So-and-So is a hack" and I honestly don't know if the person writing that piece intends it as an insult or not.
In much the same way lately, folks talk about a politician "pivoting." Some mean that the person is changing position, doing a turnabout to support that which he or she formerly opposed or vice-versa. It's like how we keep hearing that Donald Trump will "pivot" and become more presidential. I suspect we'll still be hearing that on his last day in office.
And some talk about "pivoting" as changing the subject so as to avoid answering a hard or dangerous question. The other night, Al Franken was on with Stephen Colbert and they talked a lot about "pivoting" using the latter definition.
I have no major point here; just that we should be aware that, to paraphrase Inigo Montoya, some words don't mean what some people think they mean.
