According to such scholars as G.A.Klimov and W.P.Lehmann, the early Proto-Indo-European belonged to the languages of the activestative typology or had some relics of this morphosyntactic type. In the languages like Russian, which have preserved their synthetic means of expression, the residues of the active-stative typology are still evident. In the article it is argued that in case of Russian some of these residues were «refrigerated » due to the influence of the Finno-Ugric substratum («refrigerator effect»).
