The scientific term for the vestigial tailbone all humans have is an odd-sounding word. Which of these spellings is the correct one?

The coccyx bone is more commonly known as the tailbone, and is essentially just a small, triangular bone at the bottom of your spine that kind of resembles the beak of a bird. Your coccyx bone is the junction where several tendons, ligaments, and muscles attach to each other.
