Paradigmatic pressures force uniformity within the members of a given paradigm. Nevertheless, they do not always work in a homogeneous or symmetric way. This paper is an attempt to deal with the problem of inclusion within paradigms. It shows how the Optimal Paradigms model (McCarthy  2005) and the Transderivational Correspondence Theory (Benua  1999) can be extended to apply not only within flat paradigms but also within paradigms with an internal uneven structure, in such a way that specific morphological categories or the productivity of a given derivative process are explicit in the formal machinery of the theory. The proposal is illustrated by focusing on two Romance phenomena -- overapplication of cluster reduction in Catalan and overapplication of diphthongization in Spanish -- although it can be extended to other phenomena. This account consubstantially touches other significant aspects such as the relation between the inflectional categories Gender and Number and their universal ranking as well as their interaction with derivative processes.
