A serious and widely recognized problem of the standard Binding Theory is that it has no non-circular definition of the crucial notions ‘anaphor’, ‘pronoun’ and ‘R-expression’. Burzio (1991) proposes a significant new characterization of these notions, based on their absolute and relative morphological content. Specifically, he proposes that different NP types can be distinguished by their Θ-feature content: anaphors lack Θ-features altogether, pronouns have Θ-features and no other features, and R-expressions have Θ-features plus referential information, as in (1). The Binding Theory can then be regarded as a single principle, stated in (2).
