The article presents idea of Ronald Langacker, co-founder of cognitive linguistics, about the nature of perfective and imperfective verbs. The researcher is of the opinion that the perfective verbs profile the process having a clear outline of the time. There is a change in the action described by perfective verbs and therefore these verbs are in the form inhomogeneous. Imperfec¬tive verbs are different. They profile stable situations the duration of which is indefinite in the immediate scope. Langacker compares perfective and imperfective verbs to countable and uncoun¬table nouns. He also claims that there is no feature that makes verbs as perfective or imperfective in advance. The author of the article analyzes selected sentences of The Tooti Nameh in translation of Wanda Markowska and Anna Milska.
