Chapter 6 analyzes word association responses, categorizes them into meaning-based and syntagmatic and compares to the patterns of corresponding usage corpora. It shows that words eliciting meaning-based responses tend to be independent in usage while words eliciting syntagmatic responses tend to participate in multi-word units, suggesting that word associations can indeed say something about the processes at work in language use. A deeper analysis of syntagmatic associations and their comparison to usage patterns suggest the psycholinguistic reality of the model of a unit of meaning and in particular of abstracted associations: those of colligation and semantic preference. The chapter also discusses the core meaning effect, the influence of directionality and contiguity on the strength of association, the relationship of syntagmatic association to the boundaries of a unit of meaning as well as the evidence of the processes of fixing and approximation observed in Chapter 5.

Chapter 5 compares the phraseology of usage to exposure. It shows that more than half of patterns extracted from a student’s usage corpus also occur in her exposure corpus. At the same time the figure drops significantly if these patterns are compared to a different student’s exposure corpus supporting the assumption of representativeness. The chapter then proceeds to compare usage patterns to exposure qualitatively focusing on the processes of variation and change. It finds support for the process of approximation through which a more or less fixed pattern loosens and becomes variable on the semantic or grammatical axis presumably due to frequency effects and the properties of human memory. The chapter also proposes a reverse process, fixing, through which the pattern extends and develops verbatim associations through repeated usage. Both processes are suggested to occur within meaning-shifts units and thus be characteristic of co-selection.

Chapter 2 provides an in-depth discussion of Sinclair’s conceptualization of lexis and meaning and its major concepts. It starts from the model of a unit of meaning and explains how it is capable of incorporating both syntagmatic and paradigmatic axes of meaning by including optional variable components of collocation, colligation and semantic preference. The chapter continues by offering a theoretical solution of removing the borderline between single- and multi-word units. Further it points out the difference between Firth’s and Sinclair’s conceptions of collocation and defines the relationships between the idiom principle, co-selection, syntagmatic association, core meaning, delexicalization and meaning-shift. A large part of the chapter is devoted to examining the controversy around the concept of semantic prosody. The chapter concludes by discussing Sinclair’s theory of meaning and his idea of the ultimate dictionary. The conceptualization presented in the chapter forms the theoretical backbone of the book.
