Good morning mein lieblings!
sophomoric – overly impressed with one’s own knowledge, but in fact undereducated and immature
Sophomoric seems to include the roots soph-, “wise,” and moros, “fool,” so the contrast between wisdom and ignorance is built right into the word. A high-school or college sophomore has delusions of wisdom-but only the seniors are truly wise, as we all know. Sophomoric behavior and sophomoric jokes are typical of those who have gotten a small taste of experience but think they have experienced a lot.
(I find this word quite appropriate …)
