This study analyzes speech errors to illuminate the mechanisms of language production and the nature of grammatical units. The author, Roland Pfau, draws upon grammar theory, specifically Distributed Morphology (DM), to interpret characteristic errors found in German utterances. The research focuses on two primary categories of errors: those stemming from the manipulation of semantic and morphosyntactic features, and those that appear to involve post-error repair strategies. This approach offers insights into the cognitive processes underlying spontaneous speech.

The book offers a specialized linguistic analysis, applying theoretical grammar frameworks to empirical data from speech errors. Its focus on Distributed Morphology and specific error types suggests a text aimed at academics and researchers in psycholinguistics and theoretical linguistics. The detailed examination of German utterances indicates a rigorous, data-driven approach to understanding the cognitive underpinnings of language production. The work likely contributes to ongoing debates within linguistics regarding the architecture of the grammar and the real-time processing of language.
