This research investigates the semiotic dimensions of characterization in Fawzi Sadiq’s novel 2012, adopting the semiotic method as a framework for analysis. The study examines how the multiplicity and diversity of characters—each with distinct physical, social, and intellectual dimensions—generate the novel’s internal conflicts and reflect the interplay between individual identity and societal structure. By analyzing the semiotics of names, the research highlights how personal names function as linguistic signs that reveal, reinforce, or contradict the characters’ realities and symbolic roles. It also explores the connection between characters and their temporal and spatial settings, emphasizing the narrative’s forward-looking and retrospective vision. Through descriptive, functional, and structural levels of analysis, the study uncovers how semiotic mechanisms enrich the reader’s understanding of character meaning and development. The results show that the title 2012 carries critical significance, framing a socially charged theme once prevalent in Saudi society and embodied through both realistic and allegorical characters.
