This paper presents that aspectual pairs were given in various ways in various periods, depending on the current trends in linguistics, while the essence of semantic definition, the lexical identity of imperfective and perfective verbs did not change. The essence of the modern interpretation lies in the functional approach to the determination of aspectual pairs. On the one hand, it enlarges the notion of aspectual pairs (cf. approximate pairs, aspectual partners), on the other hand, it makes obvious that the aspect and the manners of action are tightly interrelated.
The first part of the paper studies the main types of aspectual pairs, while the second part examines the variants of aspectual oppositions which are distinguished within the same type of opposition, that is, regarding even one concrete aspectual pair. In the latter case, the author suggests that a distinction should be made between strong opposition as a lexico-grammatical one and weak opposition without any lexico-semantic modification. The weak opposition is further divided into the trivial type (corresponding completely to the lexical equivalence constraint of aspectual correlates) and the privative type.
This paper discusses the question what influence the category of limitativity has on the category of verbal aspect. From this point of view, the author focuses on the semantic types of aspectual pairs, and verbs of delimitative manner of action are analyzed in this respect as well. In conclusion, the author also touches upon the aspectual model of clusters which has received special emphasis in L. Janda’s research.
