Using a 1.5-million-word sample from the CANCODE spoken English corpus, we present a description of the get-passive in informal spoken British English. Previous studies of the get-passive are reviewed, and their focus on contextual and interpersonal meanings is noted. A number of related structures are then considered and the possibility of a passive gradient is discussed. The corpus sample contains 139 get-passives of the type X get + past participle (by Y) (e.g. He got killed), of which 124 occur in contexts interpreted as adversative or problematic from the speaker's viewpoint. Very few examples contain an explicit agent or adverbials. Main verb frequency is also considered. Where contexts are positive rather than adversative, newsworthiness or focus of some kind on the subject and/or events is still apparent. The corpus evidence is used to evaluate the terms upon which an interpersonal grammar of English might be developed, and a contrast is drawn between deterministic grammars and probabilistic ones, with probabilistic grammars offering the best potential for the understanding of interpersonal features.
