The delimitative aspect is a grammatical construct that indicates that a situation lasts only a certain amount of time. It is sometimes called durative aspect. Polish: stałem i gadałem - "I stood and chatted" compared with postałem i pogadałem = "I stood and chatted for a while" (the prefix po- marking the delimitative aspect in this example).
Delimitative aspect in Chinese is often marked by reduplication of the verb. For details see Chinese grammar → Aspects.
