profound 【PROFOUND】Having taken the medicine, he fell into a profound sleep, 吃过药后，他陷入酣睡。【重点词汇】profound adj. 极深的 反: shallow

Accepted Answer

[prə'faʊnd] 
profoundsituated at or extending to great depth; too deep to have been sounded or plumbed
When you need a word that's deeper than "deep," consider profound.
Profundus meant literally "deep" in Latin, and profound had the same meaning when it entered English in the 14th century. 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 if a person tries to sound profound they're really just giving you superficial knowledge dressed up with big words.
