Ignore the copy : about the partial syncretism between ser and ir

Abstract

This article proposes a structural explanation
of the fact that in the perfective form, the verb ser is identical to ir. It is argued that internally ir is built over the verb ser, and the element that distinguishes them semantically displaces to a high position, in such a way that the lower copy left behind it is ignored for the purposes of mor
phophonological materialisation. The analysis concentrates in the perfective forms, and from there it is extended to the subjunctive imperfective.
