Grammatical Aspect

In linguistics, the grammatical aspect of a verb is a grammatical category that defines the temporal flow (or lack thereof) in a given action, event, or state, from the point of view of the speaker. A basic distinction is with regard to whether the speaker looks at a situation as bounded and unitary, without reference to any flow of time during the situation ("I ate"), or with no reference to temporal bounds but with reference to the nature of the flow of time during the situation ("I was eating", "I used to eat"). The unitary view without internal temporal flow is known as the perfective aspect (not to be confused with the perfect), while the non-bounded view with reference to temporal flow is known as the imperfective aspect. Within the imperfective aspect, further common aspectual distinctions include whether the situation is repetitive or habitual ("I used to eat"), is continuous in a particular time frame ("I was eating"), or has continuing relevance in a later time frame ("I have eaten"). Any one language has only a subset of the aspectual distinctions attested in the world's languages, and some languages (such as Standard German; see below) do not have aspects.
