Hepatitis
/ˌhɛpəˈtaɪtɪs/noun
Inflammation of the liver, usually caused by a virus, alcohol or a drug reaction.
The Greek roots
Literally: “liver inflammation”
The story of the word
The stem is the genitive ἥπατος, which is why the word is hepat- and not hepar-. The -itis ending was originally an adjective agreeing with νόσος, disease, so hepatitis is elliptically liver disease with the noun dropped, and every arthritis and bronchitis since follows that ghost agreement. The alphabet came late: the B virus was identified through Baruch Blumberg's Australia antigen in 1965, and C only in 1989.
