aspectual

Aspectual is a term in linguistics describing the aspectual properties of a verb or clause—the way events are viewed in relation to their internal structure and time frame, rather than simply at a single point in time. It concerns the speaker’s perspective on how an action unfolds, such as whether it is ongoing, completed, habitual, or repeated.

Aspect can be expressed through morphology, auxiliary constructions, or adverbial modifiers, and its realization varies by language. In English, the progressive form (I am cooking) signals imperfective, ongoing action, while the simple past (I cooked) can signal a completed, or perfective, event. Other languages mark aspect with distinct verb forms or particles; for example, some systems contrast imperfective and perfective aspects, and Chinese uses markers like le and zhe to indicate completed or ongoing states.

In linguistic theory, aspect interacts with lexical or aktionsart properties—the inherent temporal character of the verb’s meaning. Broad classes proposed by Vendler include states, activities, accomplishments, and achievements, which combine with grammatical aspect in different ways. For instance, activities like running are typically atelic and may take ongoing aspect, whereas accomplishments like building a house are telic and often align with a completed aspect.

Overall, aspectual meanings provide a grammatical framework for expressing how events unfold over time, complementing tense and mood to convey precise temporal and qualitative information about actions.
