# Of Tops and Bottoms: The Algebra of Person Case Constraints

Abstract The Person Case Constraint blocks certain combinations of clitics and weak pronouns in a variety of languages. Out of the numerous logical possibilities, only four variants of the Person Case Constraint are attested. I show that these four variants form a natural …

# An Algebraic Perspective on the Person Case Constraint

Abstract Graf (2011) and Kobele (2011) proved independently that Minimalist grammars can express all constraints that are definable in weak monadic second-order logic (MSO), i.e. the extension of first-order logic with quantification over finite sets. The proof takes as its vantage point …
