Focusing on Spanish future morphology as the property under investigation, this study contributes to the literature on heritage speaker bilingualism by exploring whether adult Spanish heritage speakers are able to distinguish between its two possible interpretations: temporal and epistemic. To this end, we present production and comprehension data from adult heritage speakers as well as from dialect-matched adult immigrants living in the United States. While both groups show robust knowledge of future morphology to express temporal futurity, our findings reveal significant differences in their access to and production of the epistemic interpretation. We document a case of convergent simplification whereby the outcome observed constitutes a reduction of the possibilities associated with future tense morphology to make Spanish more similar to English.
