Surrey Morphological Complexity Database

Morphological systems introduce an
extra layer of structure in between meaning and its expression. This layer
may operate at cross purposes to functional distinctions, attaining in some
languages an astonishing degree of complexity. Such apparently arbitrary
distinctions in form (inflection classes, irregularity and similar phenomena)
are the particular focus of this project. They are a key resource for
understanding mental processes as they represent an unconscious and yet
highly structured autonomous system.

The database was created for the project 'Morphological complexity: Typology as a
tool for delineating cognitive organization', funded by the European Research Council
under grant number 230268. This support is gratefully acknowledged.
