Structural priming has been described as a measure of association between constructions. Here, we apply priming as a diagnostic to assess the status of the Chilean second-person singular (2sg) voseo, which exists in variation with the more standard tuteo. Despite being the majority variant in informal interactions, Chileans are reported to have little metalinguistic awareness of voseo and they avoid the vos pronoun, in some cases using the tu pronoun with voseo verb forms, leading to proposals that tuteo and voseo are conflated into a single mixed form. The patterning for priming, however, indicates otherwise. Analyses of some 2000 2sg familiar tokens from a corpus of conversational Chilean Spanish reveal that a previous tuteo or voseo favors the repetition of that same form, indicating that speakers do treat these forms as distinct. We also observe that invariable forms with historically tuteo morphology are associated with neither voseo nor tuteo, while the invariable voseo discourse marker cachai ‘you know’ retains a weak association with voseo. Furthermore, while tuteo is favored with a tu subject pronoun, this effect does not override the priming effect, evidence that, even with a tu pronoun, voseo and tuteo are distinct constructions in speakers’ representations.
