With a focus on literature as a medium for the instruction of a multiplicity of skills relevant to the multinational world, this research seeks to understand the potential benefits of an interdisciplinary approach to the future of ESP. It talks about how the Algerian educational institutions are changing to accommodate the growing need for multiple-skill-based education brought about by fast-paced social and economic shifts. As fundamental abilities in today's language classes, the study focuses on the 21st Century skills, mainly the intellectualism and communication. The study's overarching goal is to improve the instruction of these abilities by bridging the gap between classroom theory and practical application via the use of interdisciplinary methodologies within the realm of literature. This is a descriptive and reviewing study. Students were observed, interviewed, and given questionnaires and post-tests as part of a mixed-method approach to data collection. Methodology of analysis deepens the exploratory and explanatory study of previous literature. The results back the incorporation of interdisciplinary literature into ESP classes and highlight the advantages of combining this with abilities needed for the modern world. We support this method since it is an effective teaching tool that improves students' knowledge and abilities.
