Derivation in Optimality Theory: A Reply to Burzio

This article argues against Burzio's (2001) reanalysis of Rubach's (2000b) glide and glottal stop insertion in the Slavic languages. It is shown that the reanalysis cannot account for the range of attested facts and that it leads to unwarranted extensions of Optimality Theory by relying on unrestricted targeted constraints. The conclusion is that Optimality Theory must admit derivational levels.
