Abstract: In this talk, I will discuss different analyses of Warner’s effects, e.g. *John was here, and Mary will too (Warner 1986). The analyses available in the literature take different stands on the identity condition on ellipsis and how it affects the acceptability of this type of example (Lasnik 1995, Potsdam 1997, Oku 1998, Merchant 2015/2016, among others). We will consider the pros and cons of each proposal regarding how English verbal morphology works and related data in Brazilian Portuguese.
