This article supports earlier work by arguing that French negative pas functions as the specifier of NegP at S-structure (at the earliest) rather than at D-structure, as proposed in Pollock's (1989) original formulation of the NegP hypothesis. After reviewing the NegP hypothesis, the author offers additional syntactic evidence to support the refinement proposed in Rowlett (1993a). He goes on to investigate parallels between the revised model and work by Williams (1991) and Fillmore (1963). Finally, he explores theoretical avenues opened up by the refined hypothesis, considering, for example, whether the distinction drawn between constituent and sentential negation is as significant as has traditionally been assumed
