Otalgia

Otaligia is a super-fancy word for earache. It comes from the Greek otalgikos (long initial O). You will note that in otalgia is the a combination of the root ot (ear) and the suffix -algia. This Greek suffix is a common attachment in medical words to indicate pain: neuralgia is a good example of that. Medicine's Classical heritage (think Hippocrates) is shown through its prolific use of Greek words.
