In linguistics, telicity (tiːˈlɪsɪti; ) is the property of a verb or verb phrase that presents an action or event as having a specific endpoint. A verb or verb phrase with this property is said to be telic; if the situation it describes is not heading for any particular endpoint, it is said to be atelic. One common way to gauge whether an English verb phrase is telic is to see whether such a phrase as in an hour, in the sense of "within an hour", (known as a time-frame adverbial) can be applied to it. Conversely, a common way to gauge whether the phrase is atelic is to see whether such a phrase as for an hour (a time-span adverbial) can be applied to it. One often encounters the notion that telic verbs and verb phrases refer to events that have endpoints, and that atelic ones refer to events or states that don't have endpoints. The notion of having endpoints applies to events in the world rather than the expressions that refer to them. This is the most criticized property of this definition. In fact, every event or state in the world begins and ends at some point, except, perhaps, for states that can be described as "the existence of the universe." Certainly, John's being angry has a beginning, and, unless John is somehow eternally angry, it also has an endpoint. Thus, it is doubtful that one can define telic expressions by means of properties of the events or states that they refer to (a very similar problem arises with the notion that mass nouns refer to things that can't be counted). Thus, recent attempts at making the notion explicit focus on the way that telic expressions refer to, or present events or states. Put differently, one can simply define telic verbs and verb phrases as referring to events conceptualized or presented as having endpoints, and atelic verbs and verb phrases as those conceptualized or presented as lacking endpoints. This type of exercise can serve as a reminder of the futility of trying to link linguistic semantics to the real world without considering the intermediary agent of human cognition.
