Abstract: The relevance of the studied problem is conditioned by the urgent need to increase the researchs concerning lacunarity problem description at the comparison of word-forming phenomena in the languages of different structures. In this study the suffix formants of subject derivatives act as the intensifying means at the level of word formation. The purpose of the study is to present the results of the field simulation comparing the word-building formants of Russian language intensification and their German counterparts. The field and functional-semantic approach were the leading approaches to this problem study. The main results of the study are the following conclusions. The field model clearly illustrates the presence of cross-language word-forming gaps and highlights the phenomenon of a cross-language word-forming lacunarity, defined as the absence in the language of translation during the search of a cross-language correspondence concerning a word-formation means equivalent to semantic SFI potential of a source language. On the basis of SFI elimination the types of word-forming lacunarity are highlighted: a potential, a relative and an absolute one. The study materials have highly practical value and can be applied in the issues of translation theory, namely at the identification of gap elimination best ways formed by SFI.
