New in paperback. Hardcover was published in 2014. Bringing together diachronic research from a variety of perspectives, notably typology, formal syntax and semantics, this volume focuses on the interplay of syntactic and semantic factors in language change - an issue so far largely neglected both in (mostly lexical) historical semantics as well as historical syntax, but recently brought into focus by grammaticalization theory as well as Minimalist diachronic syntax.
