Which of Us are Men?
The word “man” originally referred to all humans. There were malemen (“wermenn”) and femalemen (“wyfmenn”), but we were all men. About a thousand years ago a shift began that pushed “man” toward referring to penis people, and it was only as of the late 20th century that it came to be exclusively used for them. Thus, over the course of the last thousand years, people sometimes used “man” to refer to humans, sometimes only to male humans.
