Construction Grammar is one of the fastest-growing branches of functional syntax. Bringing together an international team of scholars, this handbook provides a complete overview of the current issues and applications in this approach. Divided into six thematic parts, it covers the fundamental notions of Construction Grammar, its conceptual origins and the basic ideas that unite its various branches, its solid empirical grounding and affinities with corpus linguistics, and the diverse perspectives in constructional scholarship. It highlights advances in discourse-related topics and applications to various domains, including multimodal communication, language learning and teaching and computational linguistics, and each chapter contains numerous illustrative examples and case studies involving a variety of languages. It also includes in-depth, empirically-grounded analyses of diverse theoretical, methodological, and interdisciplinary issues, alongside step-by-step introductions to the theory, making it essential reading for both researchers and students working in functional and cognitive approaches to linguistic analysis and syntactic theory.
