On the basis of empirical studies on spoken English, German, Hebrew, Swedish and French, the volume addresses the following questions: How can what initially appears to be construction x end up being construction y in on-line syntax? What are the local interactional needs which such processes respond to in the process of their emergence? Does the on-line (re-)modelling of a construction concern its syntactic or semantic side ‐ or both? And finally: Should emergent grammatical structures as they unfold in real time be seen as stages in the emerging of grammar?
