This chapter explores emergentism as a framework for understanding language acquisition, emphasizing its focus on language as a complex, dynamic system shaped by social and cognitive interactions. Unlike traditional theories, emergentism posits that language emerges from the interplay of multiple components, such as social interaction, cognitive processes, and environmental factors. Key principles include the constructive nature of learning, the importance of feedback, and the adaptive role of teachers in fostering language development. The chapter highlights opportunities for increased student engagement, creativity, and transferable skills through emergentist approaches, while also addressing challenges such as teacher training, assessment, and material design. Practical applications, such as collaborative storytelling and project-based learning, are discussed alongside criticisms of emergentism, including its potential overemphasis on social interaction and its limitations in addressing individual cognitive processes. The chapter concludes with recommendations for integrating emergentist principles into language teaching, emphasizing the need for flexible, learner-centred approaches that balance social and individual aspects of learning.
