This epilogue addresses the most important topics and challenges for the MorphosyntacticLevel in Functional Discourse Grammar that have been raised in the articles in this SpecialIssue. We begin by exploring the differences between the Morphosyntactic Level in FDGand the treatment of morphosyntactic phenomena in other linguistic frameworks. We thenconcentrate on the relevance of typological work to the construction of the formalism andto the organization of the Morphosyntactic Level. We conclude that one of its main advantages is its flexibility in accounting for the morphosyntactic diversity of the languages of the world. This flexibility is the result of three main aspects: the distinction between a configurational and a hierarchical ordering of units, the influence of external factors such asiconicity, domain integrity and functional stability, and compatibility with general observations on human language processing and production which result in a dynamicimplementation of the Morphosyntactic Level.
