The paper presents word-derivational features of verbs which co-occur with się and denote a change in the position of the body with respect to its vertical axis. The analysis shows how differences in the morphological structure of these verbs influence the manner in which the change of the position of the body proceeds. Moreover, the paper shows which elements of the meanings of verbs are carried by prefixes with which these verbs combine. The article also shows which of the morphological forms of the analysed verbs are primary, and what derivational relations hold between them and their derivatives.
