Chapters in the book demonstrate that modality involves many more syntactic categories and levels of syntactic structure than traditionally assumed. The volume distinguishes between three types of modality: 'low modality', which concerns modal interpretations associated with the verbal and nominal
cartographies in syntax; 'middle modality', or modal interpretation associated with the syntactic cartography internal to the clause; and 'high modality', relating to the left periphery. It combines cross-linguistic discussions of the more widely studied sources of modality with analyses of novel or
unexpected sources, and shows how the meanings associated with the three types of modality are realized across a wide range of languages.
