This linguist studied the way Trump speaks for two years. Here’s what she found.

“President Trump creates a spectacle in the way that he speaks,” she said. “So it creates a feeling of strength for the nation, or it creates a sense of determination, a sense that he can get the job done through his use of hyperbole and directness.”

The features of Trump’s speech patterns include a casual tone, a simple vocabulary and grammar, repetitions, hyperbole and sudden switches of topics, according to Sclafani.

As for the criticism that Trump sounds erratic when he changes subjects in the middle of a speech or sentence, Sclafani said that “this is something that we all do in everyday speech.”
