This scientific article explores the methodological aspects of teaching German as a pluricentric language, with a specific focus on the role of the Austrian national variant. Pluricentrism theory suggests that the German language is characterized by equal national variants present in German-speaking countries. Researching these national variants is crucial, as it combines linguistics with ethnolinguistics and cultural studies, providing a deeper understanding of language phenomena through an anthropocentric lens. One important aspect of studying a national language and its variants is examining the national worldview and functioning of ethnically marked vocabulary. While textbooks and manuals for teaching German as a foreign language often overlook the norms and standards of Austrian German, the existing differences between national varieties encompass all linguistic levels. Several researchers have contributed to the study of German language variability, particularly the Austrian variant. They have examined grammatical, pragmatic, and phonological peculiarities, as well as the language’s functions in various styles and contexts. However, certain issues remain unresolved, such as linguistic processes in the Austrian German vocabulary, the functional capacity of Austriacisms (Austrian-specific terms) compared to Standard High German counterparts, and the impact of Austrian language policy and media on linguistic processes. The study employs a methodology that involves analysing Austriacisms found in dictionaries and verifying their usage in Austrian newspapers. The researchers explore the lexical and semantic aspects of Austriacisms, categorizing them into three groups: Austrian realia, semantic Austriacisms with different meanings in Austria, and lexical Austriacisms used in Austria instead of German counterparts. The article presents the results of this analysis, highlighting thematic groups such as gastronomy and management/administration, which are prominent in the Austrian variant. Understanding the methodological aspects of teaching German as a pluricentric language, specifically considering the Austrian national variant, is essential for language educators. By acknowledging and incorporating the linguistic peculiarities of Austrian German into language teaching materials, educators can provide a more comprehensive and accurate representation of the language, facilitating effective language learning and intercultural competence development.
