This article presents an overview of current debates in the analysis of cleft sentences. The types of sentences that are often seen as prototypical examples of the cleft category are introduced by it is or a cross-linguistic equivalent; in addition, they have specificational semantics and a focus-background information structure articulation. It argues here that other, less prototypical types of constructions, which have received less attention, also belong to the cleft category: sentences that are introduced by expressions such as there is and you’ve got (and their cross-linguistic equivalents), as well as sentences introduced by it is which do not have specificational semantics and which express other types of information structure articulations (e.g. all-focus or topic-comment). It is argued that it is fruitful to analyse these ‘non-prototypical’ clefts in more depth, not only to come to a better understanding about these sentence types in their own right, but also to arrive at insights in the phenomenon of ‘clefts’ in general.
