The lexical aspect or aktionsart (, plural aktionsarten ) of a verb is a part of the way in which that verb is structured in relation to time. Any event, state, process, or action which a verb expresses—collectively, any eventuality—may also be said to have the same lexical aspect. Lexical aspect is distinguished from grammatical aspect: lexical aspect is an inherent property of a (semantic) eventuality, whereas grammatical aspect is a property of a (syntactic or morphological) realization. Lexical aspect is invariant, while grammatical aspect can be changed according to the whims of the speaker.
For example, eat an apple differs from sit in that there is a natural endpoint or conclusion to eating an apple. There is a time at which the eating is finished, completed, or all done. By contrast, sitting can merely stop: unless we add more details, it makes no sense to say that someone "finished" sitting. This is a distinction of lexical aspect between the two verbs. Verbs that have natural endpoints are called "telic" (from Ancient Greek telos, end); those without are called "atelic."

Famous quotes containing the word aspect:
“Whenever we encounter the Infinite in man, however imperfectly understood, we treat it with respect. Whether in the synagogue, the mosque, the pagoda, or the wigwam, there is a hideous aspect which we execrate and a sublime aspect which we venerate. So great a subject for spiritual contemplation, such measureless dreaming—the echo of God on the human wall!”
—Victor Hugo (1802–1885)
