The article is a continuation of an ongoing polemics with J. Kacala regarding the recent (1991) codification of the 'rhythmic law'. The author argues that this codification has been based on incorrect theoretical presuppositions, in particular on a concept called 'flectional-derivational zone', which considers the properties of the derivational morphemes as identical with the flectional ones. This assumption led to the codification of non-existent forms and resulted in a destabilization of the norm of the standard Slovak.
