Did You Know?
The belief system of the ancient Romans included spirits that were somewhere in between gods and humans and were thought to accompany each person through life as a protector. The Latin name for this spirit was genius, which came from the verb gignere, meaning "to beget." This sense of "attendant spirit" was first borrowed into English in the 14th century. Part of such a spirit's role was to protect a person's moral character, and from that idea an extended sense developed in the 16th century meaning "an identifying character." In time, that meaning was extended to cover a special ability for doing something, and eventually genius acquired senses referring particularly to "very great intelligence" and "people of great intelligence."
