Quantitative Perspectives on the Geolinguistic Structures of Dialect Morphology in Austria

Abstract

Abstract The traditional focus of (German) dialectology has been on spatial patterns observed in phonology. However, dialectometric approaches have generated interest in exploring geographical structures in other linguistic subsystems, including morphology. Building on this research, this study investigates geolinguistic patterns of dialect morphology in contemporary Austrian dialects using aggregative and non-aggregative measures, such as Principal Component Analysis (PCA), Multidimensional Scaling (MDS), and Cluster Analysis (CA). Data are based on a comprehensive dialect survey with 163 speakers from 40 locations across Austria, examining 120 linguistic variables related to inflection. The results show a clear geographic structuring of morphological variation, which significantly differs from traditional dialect classifications. The analysis of the linguistic basis of the geographical patterns suggests that these differences might be ascribed to methodological factors and language change. Methodologically, it is also demonstrated that the findings of aggregative and non-aggregative methods are complementary, not contradictory. Ultimately, the study underscores the importance of integrating diverse methods to gain a comprehensive understanding of geographical patterns in dialect variation.
