Selected Writings of Irmengard Rauch represents that portion of Irmengard Rauchs articles which center on contemporary and historical Germanic linguistic phenomena. They thus speak to the principal North, East, and West Germanic dialects. Her authored books The Old High German Diphthongization: A Description of a Phonemic Change (1967); The Old Saxon Language: Grammar, Epic Narrative, Linguistic Interference (1992); Semiotic Insights: The Data Do the Talking (1998); The Gothic Language: Grammar, Genetic Provenance and Typology, Readings (2003, 2011); The Phonology/Paraphonology Interface and the Sounds of German Across Time (2008) stand on their own. Her contributions to linguistic fieldwork are documented in BAGBay Area German Linguistic Fieldwork Project (2015).
Rauchs writings spanning half a century, from the early sixties to the present, encompass an array of subjects from the state of the art, to multiple language components, that is, segmental and prosodic phonological, morphological, syntactic, semantic, and pragmatic topics informing Germanic languages, as well as to literature and to nonverbal communication. Linguistic and interdisciplinary methods imbue all of her writings. At the University of Michigan, Ann Arbor, where Generative Grammar made early inroads, she was trained as an American structuralist, reaping the benefits of the functionalist Prague School, preceded by Saussure, the Neogrammarians, Darwin, Rask, Grimm (all 19th-century instigators of linguistics as a science), and of the founding of the LSA. Since the early seventies she opened her methods of analysis to the semiotic approach of Locke, Saussure, and Peirce. Consequently, Rauchs writings exploit the combined approaches of linguistics and semiotics. These are the inextricable work-horses, which in combination, enhance her arguments detailing given linguistic problems that define the field of General and Germanic Linguistics and thus feed the multi-disciplinary research interests of both seasoned researchers and neophytes.
