This paper is focused on the influence of directional prepositions and adverbs on the aspect of manner-of-motion verbs in motion events. It provides an analysis based on the British National Corpus. The aim was to find out which prepositions/adverbs encode the path of the motion with verbs denoting various ways of walking, and affect their a/telicity. Thus, the classifications provided by other authors who only mentioned the most frequently used expressions were broadened. Based on the analysis, the expressions of direction and path were divided into three groups from the perspective of their a/telicity. Since a/telicity cannot be determined easily in each situation, some factors crucial for its determining are described as well.
