This article examines future temporal reference (FTR) in the French spoken in Vimeu, a rural area of France where French evolved alongside Picard, a Gallo-Romance regional language. Unlike most French varieties, which favour periphrasis, Vimeu Picard favours the inflected form. By comparing French data from Picard–French bilinguals and French monolinguals, we assess the potential effect of Picard contact on Vimeu French. We hypothesized that bilinguals may favour the inflected form more than monolinguals, a hypothesis that was not verified. Instead, education is the best social predictor: speakers with a baccalauréat or higher disfavour the periphrastic future. Regarding linguistic constraints, we expected sentential polarity to constrain FTR (negation favours the inflected form), as in many varieties. Surprisingly, only temporal distance constrains FTR in our data: proximate events favour periphrasis, and do so even more strongly with events to occur within the minute. These results suggest that Vimeu French marks imminence through periphrasis.
