A saga (pronounced "SAH-guh") refers to any long narrative in verse or prose dealing with legendary or historic events. Like EPIC, saga is loosely used in place of such words as story, tale, adventure, exploit, and event."The voyage of the British naval ship Bounty in 1789 was a saga of the sea." "This man's rise from poverty to wealth is a story (not saga) of real-life adventure."
