A proposal for a formalized, expandable approach to the taxonomy of writing systems

Abstract

Abstract In this paper we propose a formalized and expandable approach to the taxonomy of writing systems. Taking the mixed nature of writing systems fully into account, our approach focuses on the classification of functionally homogenous subsystems, which together and in interaction with each other constitute an overall writing system. Such subsystems make use of a script or a subset of a script, which is understood here as an inventory of graphs that is (conventionally considered to be) graphically homogeneous. A basic distinction is made into phonographic and morphographic systems, but complemented by an in principle open number of subtypes, building and expanding on Gnanadesikan (2017) and Poser (1992, 2004) for segmental and syllabic systems respectively. Types are designated by a notation that employs a set of symbols, relating to both form (boundedness of graphs and their organization into segmental spaces) and function (mapping type), but by separate means.
