This article argues against the claim that the dispositional middle construction is always subject-oriented, by discussing dispositional constructions in Japanese and impersonal middle constructions formed with the causative verb lassen ‘let’. in German In Japanese, the disposition is ascribed not to the nominative subject, but to an object. in German, nominative subjects are not required. This suggests that subject orientedness is not inherent but arises from the properties of independently existing constructions that are interpeted as dispositional. In English and German, an intransitive or a reflexive construction derived from its transitive variant is employed as a canonical middle construction. In these cases, the accusative argument becomes a nominative subject by applying specific grammatical operations; thus, the expression of a subject becomes obligatory. In contrast, a potential construction is interpreted as dispositional in Japanese. In this case, the disposition is typically ascribed to the object with nominative case, which is almost obligatory in Japanese. It follows that the target of the disposition in middle constructions is a grammatically “highlighted” event participant, as in the case of root modals.
