This chapter provides an overview of empirical support for Construction Grammar in the form of behavioral evidence, that is, information derived from the behavior of language users on certain tasks, typically through controlled experiments. Three types of evidence are discussed in particular: (i) evidence from language comprehension tasks that syntactic patternsconvey meaning independently of individual lexical items, (ii) evidence that constructions prime each other both in form and in meaning, and (iii) evidence that grammar consists of a network of related constructions of varying degrees of generality. Many of the cited studies come from the psycholinguistic literature, and even though they were originally not necessarily framed in terms of constructions, their findings are largely in line with the constructional approach. Throughout the discussion, it will be shown how these findings provide evidence for some of the core tenets of Construction Grammar.

This chapter presents an overview of some of the central concepts of constructional syntax. Focusing on key insights from Berkeley Construction Grammar and Cognitive Construction Grammar, it discusses how construction entries of different types from the inventory of constructions interact with each other to license constructs. This chapter also outlines a novel methodology for discovering constructions in a corpus that allows for a systematic way of compiling construction entries that are relevant for research in Construction Grammar and constructicography.
