means A long, sprawling story that follows people or events across many years or generations, often with plenty of drama along the way.

from Straight from Old Norse 'saga,' meaning a 'story' or 'tale' — literally a 'thing said,' from the same root as 'say.' It first named the great Icelandic prose narratives of heroes and feuding families, then drifted into English to mean any epic, never-ending tale.
