This book demonstrates how a truly empirical approach to language and grammar produces theories that are completely different, almost opposed, to those dominant in Chomskian linguistics.
This is the home of the influential concepts of the idiom principle (langauage consists largely of pre-packaged chunks with their own meaning, which are varied grammatically to fit the co-text) and the open choice principle (language works as a slot-and-filler system, probably when original or difficult meanings are attempted especially when there is little or no pressure to produce). So, why is it unavailable? These ideas have helped reshaped modern linguistics, and this books sets out a methodology that anyone can adopt. Shame on you OUP.
