As we know, verbs incorporate features of change, duration and limitation and they have their intrinsic temporal qualities, such as ‘static or dynamic, punctual or durative, bounded or unbounded, continuous or iterative’ (Brinton, 1988:3). The situations (which is a cover term for events, activities and states) described by verbs can be categorized according to the features of verbs. For instance, if the meaning of a verb is punctual, the situation in the real world named by the verb could be said to be punctual, and the verb can be classified as a ‘punctual verb’.
