Did you know?

Today, the word genius tends to carry [cerebral](https://www.merriam-webster.com/dictionary/cerebral) connotations, rather than spiritual ones, but the word has its origin [in ancient Roman religion](https://www.britannica.com/topic/genius-Roman-religion), in which the genius (from Latin gignere, “to beget”) was originally a spirit who gave continuity to a family or clan over generations, and later the attendant spirit of a person or place. When genius first made its home in the English language in the 14th century it carried this “attendant spirit” meaning. Over time, the word developed the extended sense of “an identifying character or spirit,” a meaning inspired by the fact that part of a genius’s role was to protect a person’s moral character. Later genius came to refer to both remarkable talent or intelligence, and to someone who has such—genius developments, if you ask us.
