Usage-Based Motivations for Diachronic Language Change

With the understanding that language variation, whether synchronic or diachronic, is, for the most part, not random but systematic and predictable, linguists and philologists have long engaged with the task of providing accounts and explanations for how a phenomenon in a given language moves from stage a to stage b, with a temporally preceding b. A usage-based approach to diachronic change takes as its basis a fundamental link between usage and the evolution of linguistic structure through time. More specifically, motivations for language change are sought in areas that involve speakers using language and interacting with one another, such as discourse and communication, as well as cognitive processes involved in producing and understanding language. Mechanisms that contribute to language change include pragmatic inferences, frequency, (inter)subjectification and discourse management (turn-taking).
