Didactic Pedantic Adjective Inclined Teach Moralize Excessively Carries

Didactic carries with it a connotation of preachy and boring. For example: “The professor’s didactic lecture style was known for putting her students to sleep.”

Pedantic is another synonym, but it has a slightly different meaning: characterized by a narrow, often ostentatious concern for book learning and formal rules. In other words, didactic emphasizes excessive teaching, while pedantic emphasizes excessive attention to trivia, often to show off.
