Our starting point in this approach was from clinical observations and recordings of the speech of four people with Broca's aphasia, all of whom suffer from difficulties in producing sentences and oral compositions; however, we will present only one case as a model for analysis, which is the first case. These difficulties led us to the adoption of Blanche Ducarne's diagnosis test (1976), which has been adapted to the Algerian environment. This analysis has enabled us to stand on the existence of a deficit in the ability to link the different linguistic units that make up speech and enter them into relationships with one another as a result of the deletion of various grammatical tools, which led to the disappearance of these relationships, which directly affected the composition structure. This is mainly demonstrated in resorting to severe abbreviation, adopting a telegraphic speech style, together with the absence of linguistic and grammatical conjunctions.enUngrammaticalityBroca's aphasiaGrammatical disorderArticle
