And we'd talk about incorrect word usage, which would be marked with the letter "D" on his papers, to stand for "diction." Unlike many journalists obsessed with Mr. Trump's angry tweet about a "so-called judge" or his accusations that reporters were "groveling," I wasn't outraged. I immediately identified this as what I am sure it was: a diction problem. I am sure from having corrected 30-years worth of bad papers that Mr. Trump thought "so-called judge" did not mean that he was questioning the legitimacy of the judge, but rather that the judge was of poor quality. And I am equally certain that Trump does not know that "to grovel" means to crawl subserviently; he was applying it to mean almost the opposite: aggressive insistence on the part of a reporter that he found unwelcome or continuing to talk to clarify of a point.
