Etymology

The word "episode" originates from Greek epeisodion, meaning "addition" or "interlude," derived from epi- (upon) and eisodos (entry). In ancient Greek drama, it referred to scenes inserted between choral songs. Over time, it evolved to denote any incidental narrative or event within a larger framework, later adopted into Latin (episodium) and French (épisode) before entering English in the 17th century. The morpheme epi- retains its Greek sense of "upon" or "attached to," while sode reflects the idea of a "path" or "entry point" into the main narrative.
