Datapoint Diu Indo-Portuguese/Ability verb and epistemic possibility

Although the data available is not vast enough to make too strong a claim, it appears that the Diu Indo-Portuguese ability verb pude 'can' is not employed to express epistemic possibility. Instead, speakers make use of the adverb pədser 'maybe/perhaps', which is different - though diachronically derived from the ability verb (and possibly still interpreted as such synchronically).
