DO THE VERB PREFIXES EXPRESS ACTIONAL CATEGORIES?
The point of departure of the article is the presentation of the basic premisses on which the theory of aspect proposed is founded. On the basis of Slavonic facts, we want to prove that aspect has a double mode of existence: on the one hand it is a semantic component of the lexical meaning of semantemes (it is expressed covertly), on the other hand it is the meaning of aspectual grammemes eliminated from lexical meaning (it is expressed overtly). Since aspect is an inseparable component of semantemes, they don't presuppose the co-presence of aspectual grammemes. Grammemes identical aspectually with semantemes - if they are present in the structure of verbs on the virtue of some formal rules - are neutralized. On the contrary, grammemes which represent the aspect different from that of semantemes preserve it. Since semantemes have their own aspect, when combined with grammemes different aspectually, they make jointly composed aspects or configurations of aspects. Classical aspectology which attributes only one aspect to particular verbs is forced to create the category of actionalities to give an account of the aspectual configurations.There exist purely aspectual prefixes which have a status of aspectual grammemes and which make jointly with semantemes simple aspect or simpler ones in case of regressive derivation, or composed aspects (configurations of aspects) in case of progressive derivation. It turns out that some of the traditional actionalities are identical with the product of pure aspects.Apart from the verbs with pure aspectual prefixes, there are verbs traditionally included in different actional categories whose prefixes-amalgams fuse aspectual meaning with different non-aspectual meanings. One part of them have a modificational character: their non-aspectual meanings determine the meaning of semantemes. The second part have a mutational character: the prefix represent the head of their conceptual structure. In this category prefixes are functionally basic semantemes and they have their own aspect likewise radical semantemes.As a result the concept of actionality turns out to be unnecessary in the theory of aspect.
