“…Perfective aspect expresses the action as a total event summed up with reference to a single juncture, and Imperfective is characterized by the absence of that notion (Forsyth, 1972). The juncture, or position of the event's boundary, is fundamental for the Aktionsart of the verb, but the notion of perfectivity does not discriminate between the different possible positions (Bickel, 1997;Stoll, 1998). For example, the ingressive Aktionsart expresses the notion of beginning of an event, as in the verb zagovorit (zagovorit', 'start-talking.PFV'), whereas the Perfective sums up this beginning as a single undividable whole presenting it as a total event.…”
