On the probability and direction of morphosyntactic lifespan change

Abstract

AbstractThe aim of this study is to further contribute to the ongoing debate regarding the nature of “morphosyntactic lifespan change,” defined here as observable shifts in the grammatical choices individuals make between competing morphosyntactic structures. Through a quantitative case study of competition between two types of ing-nominals in seventeenth-century English, in which we factor in the grammatical contexts in which the variant structures can be used, we show that individuals vary in the extent to which they participate in the contextual diffusion of a new structure. We furthermore show that there is interindividual variability with respect to whether and what kind of lifespan change—frequency, constraint, and inventory change—is attested and highlight different patterns of intraindividual change: progressive, retrograde, and “mixed.”
