Dynamic Syntax is a formal model of utterance description that attempts to articulate and substantiate the claim that human linguistic knowledge is essentially the ability to process language in context. The model provides an explicit demonstration of how interpretation is built up incrementally from the information provided by the words as they are encountered. Drawing from a range of analyses of natural language data, the authors illustrate this new form of syntactic analysis and show how the model can be applied to a broad range of constructions and languages.
