Here are some examples:
* Aural: relating to the ear or hearing
* Auricle: the external part of the ear
* Otitis: inflammation of the ear
* Otologist: a doctor who specializes in the ear, nose, and throat
* Otoscope: a medical instrument used to examine the ear
It's important to note that both "aur" and "oto" come from Greek roots: "ous" and "otos," both meaning "ear."
