Abstract
The article deals with the modern theoretical concept in study of the variation of German phraseology abroad Germany. It is based on the synthesis of the theory of equal-righted pluricentrism with the new achievements of the cognitive linguistics. As a result the national state linguistic variant is considered as different from the regional, normatively non-codified and dialectal variation, a kind of cluster variant idiomatic thesaurus. The hypothesis of the structural isomorphy of the variant phraseology compared to the common German one has been empirically verified and vice versa - the hypothesis of the quantitative predominance in the Austrian phraseology of the structural model Adj+Sub under the Slavic linguistic influence has also been falsified
