According to well-established views language has several subsystems where each subsystem (e.g.
syntax morphology phonology) operates on the basis of hierarchically organised units. When it
comes to the graphematic structure of words however the received view appears to be that
linear structure is all that matters. Contrary to this view a sub-field of writing systems
research emerges that can be called non-linear or supra-segmental graphematics. Drawing on
parallels with supra-segmental phonology supra-segmental graphematics claims the existence and
relevance of cross-linguistically available building blocks such as the syllable and the foot
in alphabetical writing systems such as the writing systems of German and English. This book
explores the graphematic hierarchy with a special focus on the unit foot. Structural
experimental and databased evidence is presented in favour of this approach. In addition
analyses within the optimality theory framework are offered. This work shows that the
supra-segmental graphematic approaches are superior to linear ones with respect to explanatory
strength and even preciseness of the description. It is thus interesting for academics
concerned with writing systems and orthography teaching.
