The article deals with the accent of verbs on of the Ukrainian south-west dialectal array of type валbти – вfлю, валbш; варbти – вfрю, варbш; палbти – пfлю, палbш and others like that, what in literary Ukrainian have a mobile accentual paradigm валbти – валo, вfлиш etc. It is set, that actually the accent of type валbти – вfлю, валbш etc. is out of paradigm: word-parts вfлю and валbш and such others belong to the different paradigms and represent the different stages of development of the Ukrainian verbal accentual system. Endmarked word-parts of type валbш belong to that of its state, when they were endmarked with a paradigm валbти – валo, валbш and others like that. Meantime the rootmarked word-parts of type вfлю represent its modern state exactly in a south-west dialect, where such verbs consistently form the so-called second rootmarked accentual type (it is our terminology suggestion) валbти – вfлю, вfлиш and others like that, that is a dialectical alternative to the mobile accentual type валbти – валo, вfлиш and others like that of these verbs in modern literary Ukrainian.
