“…Variationist subject pronoun expression (SPE), i.e., pronombrista investigations were pioneered by Barrenechea and Alonso (1973), Morales (1980), and Bentivoglio (1980), with their studies of the Spanish spoken in Buenos Aires, Argentina; San Juan, Puerto Rico; and Caracas, Venezuela, respectively. Those seminal studies inspired the development of a sizeable body of literature that has explored the alternation between null and overt pronominal subjects in Caribbean Spanish (Alfaraz 2015;Bentivoglio 1987;Prada-Pérez and Gómez Soler 2020;Orozco 2015aOrozco , 2018aOrtiz López 2009; among others), Mainland Latin American Spanish (Cerrón Palomino 2014; Lastra and Martín Butragueño 2015;Travis 2005aTravis , 2005b, Peninsular Spanish (Cameron 1993, Enríquez 1984, Posio 2011, Prada Pérez 2009, and Spanish in the United States (Cameron 1992(Cameron , 1995(Cameron , 1996(Cameron , 1998Cameron and Flores-Ferrán 2004;Flores-Ferrán 2002, 2007aHurtado 2001;Limerick 2018;Zentella 2007, 2012;Orozco 2018b;Silva-Corvalán 1982, 1997Torres Cacoullos and Travis 2018, and others). Interestingly, pronombrista studies have made important contributions to scholarship on Spanish in the United States as well as to variationist sociolinguistics in general.…”
