Beyond Universal Grammar: Why Language Emerges from Patterns, Not Parameters

Universal Grammar (UG) proposed that humans are born with a biologically encoded set of grammatical rules. While empirical critiques have grown over time, this paper argues that UG was never epistemologically justified. It arose from a historical context that lacked models of neuroplasticity, developmental emergence, and sociocultural variation—leading to a theory more elegant than explanatory. In its place, the Pattern-Based Communication Model (PBCM) frames language as a system learned through exposure, pattern recognition, and adaptive interaction. Rather than assuming an internalized grammar module, PBCM treats language acquisition as an outcome of flexible cognition and early environmental feedback. This reframing dissolves the theoretical need for UG and provides a more accurate foundation for understanding linguistic diversity, neurodivergent learning paths, and the evolution of communication systems.
