They believed that from birth each person had one of these spirits to act as a protector. The Latin name for this spirit was genius, which came from gignere, meaning "to be the father of, beget." This sense came into English in the early 15th century. Part of such a genius's role was to protect a person's moral character. From this idea in the 16th century came the sense of genius meaning "an identifying character." This led to the sense of "a marked aptitude." In time genius came to mean "very great intellectual power" and to be applied to people who have such power.
