Diachronic change and variation in use: Judgments of clitic doubling in Peninsular vs. Rioplatense Spanish

Previous studies have demonstrated that in spontaneous speech, Rioplatense Spanish speakers - in contrast to speakers of Peninsular Spanish - sometimes produce cliticdoubled accusative nominal objects. If this contrast between varieties reflects different grammatical systems, it would be expected to also affect the acceptability of clitic doubling across varieties. We tested this hypothesis in a judgment study that compared the acceptability of dative and accusative clitic-doubled objects between Rioplatense and Peninsular Spanish speakers. Speakers of both varieties showed similar preferences with dative clitic doubling, consistent with previous work. By contrast, accusative clitic doubling was highly acceptable in Rioplatense Spanish, but not in Peninsular Spanish. Based on accounts of the diachronic development of clitic doubling, we argue that the Rioplatense speakers exhibit a diachronically advanced behavior compared to Peninsular Spanish speakers.
