"Vos" is regularly used in "paisa" (of Antioquia) Spanish, although written "vos" is considered non- normative. Recent research shows an augmented presence of written "vos" in public domains (Weyers 2016a, 2016b), which is viewed favorably by a majority of "paisas" (Weyers, forthcoming). So, what do Spanish teachers in Antioquia think about "vos?" Here we study the linguistic attitudes and self-assessed use of "vos" among a cross-section of "paisa" Spanish teachers. Quantitative and qualitative data from 61 online surveys show that over 60% of "paisa" Spanish teachers hold a favorable opinion of "vos." Specifically: (1) since "vos" is a marker of "paisa" identity, it is valued as a cultural expression; (2) 54% of "paisa" teachers consider written "vos" "correct" for some academic text types; (3) "vos" is not considered less "correct" than "tú" in the Spanish classroom; (4) "vos" is more common in university settings than in high school, where "usted" is regularly used; and (5) over two-thirds of Spanish teachers include "vos" in their grammar instruction irrespective of its appearance in their course materials. Might "vos" become more normative in Antioquia? The results suggest that there is no identifiable barrier to impede its evolution.
