Other forms: feuds
A feud is a long bitter quarrel between families or groups. It outlasts whatever started it.
The length is essential, since a feud runs for years and often for generations, by which point nobody quite remembers the original offence. Historical feuds between clans and families are the classic kind. The word is now used more loosely for any prolonged public quarrel, so a feud between two celebrities is a standing story. As a verb, feuding families are still at it. Vendetta is the Italian word for the same thing.
