Spanish Anticausative Inherent Reciprocals and Syntactic Reciprocals with Se*

Within the debate about heterogeneity of unaccusative structures, aim this paper is to distinguish two types Spanish marked anticausative inherent reciprocals (AIRs) from other syntactic (SRs) with se. Several diagnostics show that AIRs such as mezclarse ‘get mixed’ are symmetric, unaccusative, telic, and causative alternations, while SRs transitive vary in their aspectual properties do not alternations. The en/durante ‘in/for’ adverbials test reveals there AIRs: achievements casarse married’, degree mixed’. Although clitic an agreement marker these reciprocal constructions, it expletive voice head casarse, a mezclarse, anaphor merged internal argument position SRs. Differences between depend on semantic associated respective event structures.
