But even then, it also meant “figuratively deep” — that is, very great or intense: “The new laws have had a profound impact.” Of people, it means “very knowledgeable or insightful,” but sometimes when a person tries to sound profound, they’re really just giving you superficial knowledge dressed up with big words.
