From the introduction: "In this squib, I want to draw attention to some previously unnoticed but intriguing facts about inalienably possessed NPs (INPs) in Brazilian Portuguese (BP). I argue that these differ from both pronouns and anaphors in that (i) they must always be c-commanded in their minimal Complete Functional Complex (CFC) by an argument with an independent θ-role and (ii) the Binding Theory (BT) applies to IPNPs algorithmically: first the BT attempts to treat them as anaphors; if successful, the BT is satisfied; if not, then it treats them as pronouns."
