The aim of the study was to introduce usage-based approaches to language in the context of aphasiology and speech language pathology and to demonstrate the benefits of employing theoretical linguistic models in the study, diagnosis, and therapy of language impairments and the benefits of feeding the results of aphasia research back into the construction of such models. This is illustrated by a case study of lexical retrieval problems and paragrammatic errors in the speech of a person with conduction aphasia.
