Which medical term describes inflammation of the ear?

The term that refers to inflammation of the ear is "Otitis." This word derives from the Greek word "otis," which means ear, and the suffix "-itis," which indicates inflammation.

Otitis can refer to various types of ear inflammation, including otitis externa (inflammation of the outer ear canal) and otitis media (inflammation of the middle ear). This makes the term specific to ear conditions.

Other terms provided relate to different anatomical areas or conditions: colitis pertains to inflammation of the colon, pneumonia refers to inflammation of the lungs, and sinusitis is the inflammation of the sinus cavities. Each of these terms involves inflammation in a different part of the body, which is why they do not apply to inflammation of the ear specifically.
