Tracking linguistic change in childhood: Transmission, incrementation, and vernacular reorganization

Abstract:The mechanisms underlying linguistic change are well documented for adolescent and adult speech, but much less is known about how such change emerges in the childhood years. In this article we address this gap by conducting a real-time analysis of the acquisition of a rapidly expanding variable in young speakers, first in preschool and later in preadolescence. By tracking a variable undergoing change at two key stages of sociolinguistic development, transmission and incrementation, we observe directly the processes operating on individual and community grammars as children shift to the leading edge of change.
