This study examined the relationship between trait emotional intelligence (EI), narrative theme, and English proficiency in shaping the emotional vocabulary used by Saudi university students when recounting autobiographical experiences of guilt and loneliness. Ninety-three participants completed the TEIQue-SF and produced two 20-minute narratives in English, which were analysed for emotional language using SEANCE, a natural language processing tool, alongside thematic coding. By exploring how EI and narrative content intersect with language use, this research highlights the role of personal dispositions and memory focus in the development of learners’ expressive capacity in L2 writing.47enemotionsL2 vocavularyemotional intelligenceThesis
