Marco Bruckmeier, Aspektmarkierung im Mittelhochdeutschen. Untersuchungen zur präfixgesteuerten Perfektivierung und verbalen Paarigkeit. Germanistische Bibliothek, 85. Heidelberg: Universitätsverlag Winter, 2025, 247 pp.

This study is the published form a recent (2024) dissertation from the Otto-Friedrich-Universität Bamberg on gi- prefixed verbs in diachronic perspective, not only within the Middle High German, but also from the Old High German period. Alongside providing an inventory of all such verbs in both periods, the author studies the diachronic grammaticalization processes leading ultimately to widespread de-aspectualization in German by the early modern period. The collected corpus provides a basis for distributional, morphological, and semantic analyses within a typological framework that accounts for structural reorganization and changes in the aspect system over time. Apart from the introduction, conclusion, and back matter, three body chapters cover foundational aspect-theoretical terms and approaches, the interaction of aspect and grammaticalization, and aspectualization, and verbal pairs in Old and Middle High German (the corpus analysis).
