Modals and Quasi-modals in English reports the findings of a
corpus-based study of the modals and a set of semantically-related
‘quasi-modals’ in English. The study is the largest and most comprehensive
to date in this area, and is informed by recent developments in the study
of modality, including grammaticalization and recent diachronic change. The
selection of the parallel corpora used, representing British, American and
Australian English, was designed to facilitate the exploration of both
regional and stylistic variation.
