“…The seemingly incongruous appearance of the realis su x in the doubly irrealis construction is reminiscent of 'fake tense' and 'fake aspect' found in counterfactual conditional constructions in many languages (see, e.g., Bjorkman and Halpert to appear, Fleischman 1989, Iatridou 2000, Van Linden and Verstraete 2008. In the counterfactual constructions in question, morphemes that in other constructions indicate past tense, perfect aspect, or imperfective aspect, enter into a construction where they no longer mark the tense or aspect that they do elsewhere, but rather contribute to the counterfactual conditional meaning of the construction.…”
