What does hepatitis mean?
Hepatitis is the medical term for inflammation of the liver. It may be short-lived (acute) or persistent (chronic), and its causes include viral infections, autoimmune disease, alcohol, medications, and other toxic exposures. The best-known forms are viral hepatitides A, B, and C, each caused by a different virus; the letter is part of the medical name, not an abbreviation. In general use, “hepatitis” often suggests a viral illness, especially when no cause is specified, but the word can also refer to noninfectious liver inflammation. Symptoms can include fatigue, nausea, abdominal discomfort, and jaundice, although presentation varies. The word matters in both clinical and public-health contexts because different forms differ in transmissibility, treatment, and outlook. Acute cases may resolve, while chronic hepatitis can cause ongoing liver damage and, in some cases, cirrhosis. Understanding the modifier attached to “hepatitis” is therefore essential: it helps identify the cause, route of transmission, available treatments, and need for vaccination or other preventive measures.

Where does hepatitis come from?
The word is built from Ancient Greek hēpar, with genitive hēpatos, meaning “liver,” and the suffix -itis, meaning “inflammation.” In medical terminology, hepat- became a combining form for the liver, as in hepatic, hepatocyte, and hepatology. The resulting name transparently means “inflammation of the liver.”
