The influence of semantic factors on auxiliary selection, the circularity of the arguments in favor of an unaccusative treatment of verbs of manner of motion and verbs of sound emission on a directed motion use on the basis of resultative data, and the lack of clear patterns in the causativisation data for these verbs indicate a need to find stronger evidence in favor of a treatment of these verbs as underlyingly unaccusative. These problems do not, however, necessarily mean that 's analysis of the resultative construction and in particular the argument structure of these verbs is incorrect. They simply indicate that their explanation has not as yet been adequately motivated in the case of these verbs. However, even if we were to accept the evidence provide for their account of the treatment of verbs of manner of motion, there remain several semantic issues which are inadequately or incorrectly handled in their approach. I turn to those issues in the next section.
