Trivia refers to obscure or useless information, but this definition is a far cry from the word's etymology. Trivia, or tri-via, literally means "three roads," and in Ancient Roman times, it referred to three-way intersections. These heavily trafficked intersections were places where common people would chat, trade, gossip, and bicker, and it is in this context that the seeds of our modern sense of the word were first sown.
