We support Cermak, Sgall and Vybiral's (2005) call for discussion on standard Czech. Based on the empirical data summarized in this paper, we argue that the non-literary varieties of Czech, at least as far as they are used in unofficial public and semi-public discourse, should be considered a part of the colloquial standard Czech rather than 'substandard' (inter)dialects. We emphasize two basic assumptions: 1) language should not be regulated, and 2) continuity of the standard should be maintained. Standard Czech could be defined as the union of two clearly distinguished notions - Literary Czech (as the core) and the completed colloquial layer, with a penetrable boundary in between the two.
