Drawing on usage-based theory, neurocognition, and complex systems, this book elaborates an elegant model accommodating accumulated insights into human language even as it frees linguistics from its two-thousand-year-old, ideological attachment to reified grammatical systems. Idiolects are redefined as continually emergent collections of context specific, probabilistic memories entrenched as a result of domain-general cognitive processes that create and consolidate linguistic experience. Also continually emergent, conventionalization and vernacularization operate across individuals producing the illusion of shared grammatical systems. Conventionalization results from the emergence of parallel expectations for the use of linguistic elements organized into syntagmatic and paradigmatic relationships. In parallel, vernacularization indexes linguistic forms to sociocultural identities and stances. Evidence implying entrenchment and conventionalization is provided in asymmetrical frequency distributions.
