What does pinnal mean?
Pinnal is a technical adjective meaning relating to the pinna, the externally visible part of the ear. It is used to describe features such as pinnal cartilage, the connective framework supporting the outer ear, and the pinnal surface, including the skin and contours of the pinna. The word is especially associated with anatomy, medicine, and veterinary science rather than everyday speech. Although the external ear is a familiar feature of the body, specialists distinguish its different components precisely, and “pinnal” provides terminology for that anatomical precision. In general writing, an expression such as “the outer ear” or “the auricle” will usually be clearer unless the context is specifically technical.

Where does pinnal come from?
Pinnal was formed from the Latin noun pinna, meaning “feather” or “wing” and also used for the external ear, together with the adjective-forming suffix -al. The anatomical sense developed through the established use of pinna for the external portion of the ear. English pinna and related forms such as pinnate and pinniform also trace their names to the same Latin word.
