The problem of subjective modality in the Functional Grammar model

The purpose of this paper is twofold. I will first propose a number of modifications to the analysis of subjective modality in the Functional Grammar model (as developed in Hengeveld 1987, 1988, 1989, Dik 1997), using the English modal auxiliaries as a test case. I will then confront the alternative view of subjective modality resulting from these modifications with the architecture for FG proposed in Hengeveld (this volume). I will show how the proposed modifications can be dealt with more easily in the modular, top-down architecture than in the traditional FG model, but I will also argue that some further change is required in the model, more particularly concerning the optionality of layers at the representational level.
