This introduction discusses current trends in diachronic linguistics with a focus on syntactic change and reviews the fifteen other chapters included in the volume. In the spirit of modern diachronic syntax, the selected articles show that very general patterns of change, emergent, multigenerational diachronic phenomena, interact with small, discrete, local, intergenerational changes in the lexical specification of grammatical features. General topics include acquisition biases, cross-categorial word order generalizations, typological particularities and universals, language contact, and transitional changes, while specific linguistic topics include tense and viewpoint aspect, directional/aspectual affixes, V2, V3, Stylistic Fronting, directional/aspectual prefixes, negation, accusative and dative marking, analytic passives, complementizer agreement, and control and raising verbs.
