(By Maria Polinsky): "An antipassive construction is a derived detransitivized construction with a two-place predicate, related to a corresponding transitive construction whose predicate is the same lexical item. In the basic transitive construction, the patient-like argument is realized as a direct object; in the antipassive construction, that argument is either suppressed (left implicit) or realized as an oblique complement. The term antipassive (Silverstein 1972) was coined to indicate that the construction is a mirror image of the passive: in the passive, the suppressed or demoted argument is the agent-like argument, in the antipassive, the patient-like argument."
