ABSTRACT
This chapter shows that concerning the problem which the interaction of deletion processes and other types of phonological rules pose for the Koutsoudas, A., G. Sanders and C. Noll (KSN) hypothesis, attention is drawn to a case from the Australian language, Lardil. It also shows that the 'self-feeding' effect is achieved in the modified version of phonological theory proposed by C. Douglas Johnson by specifying a rule for the direction. In the development of phonological theory, the 'feeding' effect is achieved either by extrinsically ordering the rules, or by the principle of maximal utilization of rules proposed in Paul Kiparsky, or by the newer principle of minimization of opacity adopted in Kiparsky. There are several aspects of Odawa phonology which strongly suggest that the KSN theory of Universally Determined Rule Application cannot capture all the generalizations about natural language.
