Here's the title of an Associated Press piece on Trump's "unmistakably distinct" speaking style.
Trump's speaking style still flummoxes linguists
Which is a nice, polite way to put it. Linguists are flummoxed by the "rambling, aside-filled bursts" and "self-congratulatory bravado." The proximate cause for their flummoxation is the recent AP interview with Trump, in which the leader of the nation blusters and squirms like a grade-school child trying to convince his teacher he did indeed do the homework, but he did it in invisible ink on the skinned hide of a unicorn only visible during the full moon and only if you believe it exists.
The linguists, however, do not sound all that flummoxed from here. They seem downright at peace with the antics of Shouty McShoutface.
"I don't know that any president has ever used 'super-duper' in his rhetoric before," Du Mez said. Still, while she said the president is sometimes mocked for his elementary word choices, "In terms of oral rhetoric, you want a simpler grade level. That's a more effective way to communicate."
Not addressed by the linguists: the part where he lies through his teeth. The part where he interrupts whatever he's supposed to be saying to drift into a long aside about his own greatness. The part where, when asked a question about any specific issue or policy, he invariably simply spouts words about how "important" the thing you're talking about is without giving even the barest hint he has ever thought about it before or will think about it in the future. What's important here is that the sitting president speaks in simple language, the language of the common clay. The common clay doesn't abide folks who know what the nuclear triad is, or who particularly care if the latest existential menace outside their door is real or imagined. As linguists will assure you, they just want it dumbed down. If it can't be stitched on a hat they'll just resent you for wasting their time.
So this is something, anyway. The psychiatrists are officially Freaked Out, and the ethicists have given up and have resorted to day drinking, but the linguists are merely flummoxed by Trump. In today's world merely being flummoxed counts as having a pretty damn good day.
