Margarita Jara (World Languages and Cultures) co-authored “The Microvariation of the Spanish Perfect in Three Varieties” with Paz Gonzalez and Carmen Kleinherenbrink (both of Leiden University), which appears in Isogloss, a journal on variation on Romance and Iberian languages. This study investigates the variability in the use of the preterit canté (‘I sang’) and the present perfect he cantado (‘I have sung’) across three Spanish dialects: Peninsular, Peruvian, and Argentinian. The results of this research seek to contribute to the description of dialectal differences with respect to the use of the preterit and the present perfect from both a quantitative and qualitative perspective.
