This study investigates the role of isolation in shaping narrative structure within contemporary Saudi fiction, approaching isolation as a complex human condition that reveals the dynamics of self-awareness under psychological and social pressures. By analyzing selected Saudi novels, the research demonstrates how isolation becomes a narrative engine that drives events, influences character development, and organizes the internal structure of the story. The study shows that isolation functions not only as a thematic element but also as an artistic and semantic device that expands the expressive depth of the narrative. One of its most notable effects appears in the transformation of place: open spaces become metaphorically closed due to the character’s detachment, while enclosed spaces become increasingly restrictive, reflecting the character’s emotional confinement. The findings further indicate that the isolated character plays a decisive role in constructing the identity of place, as spatial perception is closely tied to psychological states. Moreover, the emergence of psychological time is shown to result from emotional shocks and intense experiences faced by isolated characters, leading to a temporal perception that diverges from objective physical time and instead unfolds as internal, subjective time.
