“…This line of research falls largely, of course, into the classical Labovian idea of experimentally exploiting present reactions of speakers to uncover processes that can be relevant for language change more generally. And just as naturally, our approach shares more with recent attempts to explain paths of change in the area of meaning (rather than sound change or morphosyntax as in Labovian studies), such as Zhang, Piñango & Deo (2018), Fedzechkina & Roberts (2020), Fuchs, Deo & Piñango (2020), Gergel, Kopf-Giammanco & Puhl (2021), Puhl & Gergel (2022). Returning to the general question regarding presuppositions, our paper addresses it by considering one single case of a presupposition trigger, the lexical item corresponding to the meaning of the quantifier both.…”
