ABSTRACT
In this text, I study three constructions that have changed in Brazilian Portuguese (BP), namely anticausatives, as in (1) The plate (se) broke; middles, as in (2) These clothes (se) wash easily; and impersonals, as in (3) In this place (se) sell boots. These constructions were obligatorily marked with the clitic SE in previous centuries. I argue that the structural changes in these events have a common source: the loss of the clitic SE which is the nucleus of a specific Voice projection.
Key-words: clitic SE; Voice projection; Brazilian Portuguese
