Variación en forma morfológica de los pronombres de primera y segunda persona de plural

in this article we analyse a property of personal pronouns in spanish which, to the extent of our knowledge, has not been studied in depth in the previous literature: the fact that the first and second person plural pronouns are morphologically com- plex (nos-otros, ‘us-others’, vos-otros, ‘you-others’). We propose to relate this phenom- enon with another typological exception which spanish exhibits: the discordances in person with some plural subjects (los estudiantes queremos aprobar, ‘The students want.pl pass the exam’; los estudiantes queréis aprobar, ‘The students want.2pl pass the exam’). in a strictly syntactic framework for the study of morphological processes we will propose that both phenomena are related to each other as consequences of the same strategy to avoid a semantically uninterpretable configuration.
