It can be used in a few different ways:
* Anatomically: It can describe something located in the ear or relating to the ear's structure. For example, "auricular cartilage" is the cartilage that forms the outer ear.
* Medically: It can refer to treatments or conditions related to the ear, like "auricular acupuncture" or "auricular hematoma" (a blood clot in the ear).
* Figuratively: It can sometimes be used to describe something that is heard or perceived by the ear, like "auricular evidence" referring to something heard as proof.
So, the word "auricular" essentially means "of or relating to the ear".
