The purpose of this paper is to clarify the need to create aspectual roles. The `Measuring-out argument` which have functions to delimit situation, measure out the event. This corresponds to `aspectual roles`: [MEASURE], [PATH], [TERMINUS]. We discuss the aspectual roles, linking constraints, and the relationship between aspectual and thematic roles. [MEASURE], [PATH], [TERMINUS] are aspectual roles, and they are linked to syntactic argument according to the linking principle. [MEASURE] is linked to direct internal argument. [TERMINUS] is linked to direct internal argument, or to the adjunct which is added for bounded reading. In some cases [PATH] is explicitly represented, however, it is not if/when one argument is linked to [TERMINUS]. There are differences in thematic roles and aspectual roles, especially in the aspectual information. For instance, the linking of `Theme` and [MEASURE] are different according to certain circumstances. As we establish the aspectual roles, we can explain the aspectual function of argument, and we can relate the argument to semantic realities (aspectual roles). Aspectual roles make up two aspectual role grids: one being [[MEASURE]], the other being [[PATH], [TERMINUS]].
