Interchahge of the illative and postpositions in the Komi-Permian language

The Komi-Permian language referring to the Permian branch of the Finno-Ugric languages, has the developed case system, the quantity of cases in dialects varies from 18 to 28. The basic part of the paradigm of declination is made of local cases. The illative is spread in all Permian languages, its indicator (кз. кп.-ö, удм.- e ) was formed on the basis of the final vowel stem after loss of lative suffix*- k. The spatial use of the illative is connected with expression of orientation of movement to the internal zone of the orientator which includes the orientator itself and, if the orientator is volumetric, the space inside the orientator. In the internal zone the surface and the internal part of the orientator differ. At expression of spatial relations several spatial postpositions can compete with the illative.Interchange of the illative and the postposition pyсk ö ‘in, inside’ (localization IN) is marked at expression of orientation of movement to the internal part of the orientator.Interchange of the illative and the postposition vyl ö ‘on’ / superlative (localization SUPER) is observed at expression of movement, moving of object to the orientator surface.Interchange of the illative and postpositions vyl ö ‘on’, jyl ö ‘on’ (localization APEX) is possible in the contexts describing movement, directed from below upwards.Interchange of the illative and the postposition berd ö ‘to’ (localization CONT) is possible at expression of contact of the object with the orientator.Interchange of indicator of the illative and the postposition оrd ö ‘to’ (localization DOMUS) is marked at expression of orientation to the place of residing of the person.Thus, in the Komi-Permian language the illative can interchange with the spatial postposition at expression of orientation of movement both to the internal part, and to the surface of the orientator. Such situation testifies that in case of use of an indicator of the illative physical properties of the orientator are not relevant, it does not matter whether the orientator possesses an internal cavity. In each of the contexts it shows that the object is directed to the internal zone of the orientator. Unlike the illative, the use of postpositions correlates with physical characteristics of the orientator, each of the interchanging postpositions is used in certain type of the context. The illative and a postposition in the same types of contexts can act as doublet means, at the same time the choice of the grammatical form can be connected with the prospect choice, with various comprehension of the spatial situation. Interchanging units differ by frequency characteristics in types of the contexts. At expression of the orientation of movement to the internal part of the orientator the primary use of the illative is observed, at expression of orientation to the orientator surface the use of post-positions is preferable. Expansion of ability of the use of postpositions in noun phrases, the tendency of replacement of the illative to periphery can be explained by semantic specialization of postpositions, and also by influence of the Russian language on the Komi-Permian one.
