ættum

Þættir, in Icelandic literary terminology, are short narrative episodes or tales, often embedded within longer sagas or presented as compact standalone pieces. The singular form is þáttr, and the plural is þættir; in the dative plural the ordinary form is þættum. The word derives from Old Norse and denotes a concise narrative unit, sometimes contrasting with a full-length saga.

In medieval Icelandic literature, þættir function as brief, self-contained episodes that illuminate a character, event, or backstory. They may appear as interludes within a saga, providing rapid development, a moment of humor, or a dramatic turning point, rather than as extended, sequential chronicles. Their subjects range from legendary deeds to political intrigues and personal encounters, often highlighting dialogue and vivid scenes.

Formally, þættir tend to be shorter and more focused than sagas, with tighter plotting and a concentrated narrative arc. They frequently rely on pointed dialogue, a brisk pace, and a clear focal moment that stands apart from the broader saga. Because of their episodic nature, they can function as narrative bridges, mood setters, or character sketches within a larger text.

In modern scholarship, the distinction between a þáttr and a saga is discussed in terms of length, scope, and narrative technique. Þættir are valued for their compact artistry and their ability to convey characterization and atmosphere in a brief space. They are studied as an important component of medieval Icelandic prose and as a window into storytelling practices of the period.
