-- Magisterial, Dogmatical, Arrogant. One who is magisterial assumes the air of a master toward his pupils; one who is dogmatical lays down his positions in a tone of authority or dictation; one who is arrogant insults others by an undue assumption of superiority. Those who have long been teachers sometimes acquire, unconsciously, a manner which borders too much on the magisterial, and may be unjustly construed as dogmatical, or even arrogant.
