Tiwa (Tibeto-Burman; India) has two series of epistemic indefinites: one whose epistemic effects arise via an anti-singleton constraint similar to Spanish algúun (Alonso-Ovalle and Menéndez-Benito, 2010), and another, wide-scope indefinite whose epistemic effects must be derived differently. I propose that for these latter indefinites, ignorance arises not through domain constraints, but as a result of their choice functional nature through competition with other indefinites. Tiwa’s wide scope indefinites then constitute a new kind of epistemic indefinite, showing that ignorance implicatures for indefinites can arise through different sorts of competition.
