On Multiple Source Constructions in Language Change

In much writing on language change, there is a tacit assumption that change operates on a single source construction to produce an innovative target construction. This volume challenges this assumption, by showing that many changes involve interactions between multiple source constructions. In fact, the involvement of multiple source constructions is unexceptional. The phenomenon is observed in phonology, morphology, syntax and semantics. It is seen in language-internal change as well as in cont
