IPA: /oʊˈtæl.dʒə/
KK: /oʊˈtæl.dʒə/
A condition characterized by pain in the ear, commonly known as an earache.
After swimming, I developed otalgia and had to see a doctor.
Otaligia is formed from "oto-" (from Greek "ous, otos", meaning ear) and "algia" (from Greek "algos", meaning pain). The word refers to pain in the ear.
Think of 'oto-' meaning ear and 'algia' meaning pain — so otalgia is the pain you feel in your ear.
