The variable use of determiners in Old French and the argument DP hypothesis

The argument DP hypothesis, adopted by many syntactic analyses, claims that nominal arguments are introduced by a determiner (D), which may be covert or overt. While overt D is obligatory in Modern French (consistent with the argument DP hypothesis), it was not obligatory in earlier stages of French. We explore the factors that contributed to this change – including semantic class, syntactic function, number, and definiteness – focusing on a shift that occurred in the D-paradigm in two Anglo-Norman texts of the 12th century. Quantitative analysis (Goldvarb) yields two major findings. First, the effect of syntactic function remains constant: subject position favours overt D, but object position inhibits it. Second, there is a change in the effect of semantic class: count nouns increasingly favour overt D, but non-count (mass and abstract) nouns increasingly inhibit it. More generally, the gradual disappearance of bare Ns in French reflects the emergence of paradigmatically conditioned D.
