"[At CPAC] Trump manifested a number of phonemic paraphasias. He was trying to say evangelist, for example, but haltingly said "evangelish." He was trying to say "three years later," but said, "three years, lady, lady, lady." Trying to spit out the word "lately," he sounded like a car with a bad battery struggling to turn over. When Trump can't find a word his whole demeanor changes. It's almost like someone pulled the metaphorical plug. Trump looks blank, stops in mid-sentence (or mid-word), his jaw goes a little slack, and when he starts to talk again, he slurs, speaks haltingly, and often looks confused. Trying to get the word out, he shifts to a non-word that is easier to pronounce. When people are losing their ability to use language they use non-words. They start with the stem of the real word, and then they improvise from there."
