Mapping Disciplinary Variation in Syntactic Complexity: A Corpus‐Based Study of German Research Article Abstracts

ABSTRACT This study investigated syntactic complexity in research article abstracts across six disciplines in German. Drawing on a corpus of 6480 abstracts from core journals, the analysis employed a framework comprising 16 measures to examine disciplinary variation in Linguistics, Sociology, Political Science, Medicine, Civil Engineering, and Telecommunications. The findings indicate notable disciplinary variation. Linguistics shows a strong tendency toward clausal elaboration through subordination. Sociology and Political Science display comparable patterns, combining clausal complexity with frequent use of complex nominals at the T‐unit level. Medicine is distinguished by the dense use of phrasal constructions at the clause level, with long clauses featuring a high nominal density. Civil Engineering and Telecommunications constitute a closely aligned group, both favoring phrasal complexity as a strategy for informational compression. Taken together, these results suggest that disciplinary discourses exhibit distinctive syntactic preferences aligned with their epistemological orientations and communicative practices. The findings help to enhance understanding of disciplinary writing conventions and provide pedagogical insights for German academic writing instruction.
