The case of sudden stroke stroke aphasia presented in this chapter concerns Elisabeth, a French teacher (Yaneva-Nedeva, 2017). This study is part of the paradigm of general linguistics, language didactics, and theoretical and remedial neuro-psycholinguistics. Elizabeth is aphasic and she has motor sequelae, with some disorders of oral expression (sub-agrammatism) but a good verbal and written comprehension. The didactics of languages is approached, to show the interest of its application to the rehabilitation of the language of aphasic subjects, via the notion of "preceptorship" (Jacquet-Andrieu, 2012). Aphasia is a drama experienced by the person and his entourage. To offer aphasic patients care in respect of their human dignity, respecting medical ethics and without their being infantilized, we will draw on the variety of methods of language didactics. A relationship of trust is established in the care relationship over time that will explain how the linguist becomes a therapist and how he models the process of care through various methodologies, the purpose being to observe the strengths, linguistic progress at the end of the experiment.
