Spatial and temporal boundedness in English motion events

This study examines how reference to spatial boundaries can make speakers of English represent or understand a motion event as temporally bounded. Spatial boundaries can be implied by (a) the path expressed by a directional item, (b) the so-called ―landmark‖ (Langacker, 1987) serving as ̳support‘ for the path, and (c) the moving entity. Importantly, one and the same entity in the real world can also be conceptualized as either primarily delimited (bounded) or extended (nonbounded). After setting the stage with an example (section 1) and dealing with some important terminological preliminaries (section 2), we take a closer look at the concept of boundaries (section 3). We then set up a four-way classification of directional prepositions in English (section 4), based on whether they refer to a path that is extended and, if so, on whether that path is specified or not for having or lacking an end-
