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:
“An actress reading a part for the first time tries many ways to say the same line before she settles into the one she believes suits the character and situation best. There’s an aspect of the rehearsing actress about the girl on the verge of her teens. Playfully, she is starting to try out ways to be a grown-up person.”
—Stella Chess (20th century)
