Carnal knowledge

Carnal knowledge is an archaic or legal euphemism for sexual intercourse. The term derives from the Biblical usage of the verb know/knew, as in the King James Bible and other versions, a euphemism for sexual conduct. An example of this usage is in the first part of the Bible, the Book of Genesis, which describes how Adam and Eve created their first child: "And Adam knew Eve his wife; and she conceived, and bore Cain, and said, I have gotten a man with [the help of] Jehovah." – Genesis 4:1.
