The volume on word formation is the third part of a comprehensive new grammar of Middle High German. It is the first study to process and present MHG word formation from the systematic foundation of a comprehensive structured corpus of MHG manuscripts (1070–1350). Thus the volume closes a gap between the approaches to presenting OHG word formation and the various studies of word formation in Early New High German. The account of MHG word formation mainly follows a semantic approach and presents word formation from semasiological and onomasiological perspectives. The presentation combines modern linguistic methods with traditional philological approaches and should be of use both to linguistics and medievalists from different disciplines.
