Etymology: Ancient Greek physicians named the liver "hêpar," and the Greek word has an unexpected Indo-European pedigree: it traces back to a reconstructed root that also gave rise to words for the liver across several branches of the family. The Romans borrowed it as "hēpar," and Latin physicians then built "hēpatītis" from it, using the classical suffix "-ītis," which was used to name inflammatory conditions. Medicine's "-itis" pattern, as in "arthritis" or "tonsillitis," works the same way, so the word simply means "inflammation of the liver." The name is a neat example of how classical medicine was built from ordinary body parts plus a standard label. Because the "-itis" ending marks inflammation, the word had to describe an inflamed liver specifically, whatever the cause. Modern readers may find it surprising that the term is a deliberate Latin coinage rather than an old folk name, and that English took it over whole in its medical vocabulary.

Synonyms: liver inflammation, liver disease, viral hepatitis, chronic hepatitis, autoimmune hepatitis
