Focalization, primarily used in literary theory, refers to the perspective through which a story is told. It's not just who is speaking (narration), but who is 'seeing' or experiencing the events. Imagine it as the lens through which the reader perceives the narrative. There's internal focalization (seeing through a character's eyes) and external (observing from the outside). It dictates what information is filtered and how it's presented to the audience.
