The main objective of this research is to characterize the form and the semantics of the transitive arguments lexical subject and direct object in transitive constructions throughout the history of the Spanish language. Firstly, this paper presents the analysis of the internal structural complexity of the subject and the direct object. Secondly, it shows the evolution of the features ±human and ±concrete of both arguments. The hypothesis is that Spanish has experienced a weakening of the typical lexical-semantic features of transitive arguments in parallel to an increase of their internal structural complexity. The quantitative evidence is supported by z statistic proof.
