This chapter offers a practical introduction to a set of corpus-linguistic analytical methods that are referred to collectively as ‘collostructional analysis’. The overarching aim in conducting a collostructional analysis is to find out which lexical items form collocations with a given grammatical construction. The purpose of such an undertaking, in the context of this book, is to facilitate the semantic analysis of grammatical constructions. The chapter discusses several case studies in order to show that the semantic description of grammatical constructions benefits from a quantitative analysis of the lexical material that occurs with the respective constructions. A final discussion surveys advantages and pitfalls of collostructional methods.
