Agrammatism is a language impairment characterized by difficulties in producing or comprehending grammatical structures, particularly those involving function words, inflectional morphology, and syntactic relationships ^[1][2]. It is commonly associated with nonfluent aphasia and may manifest in reduced grammatical complexity, omission of articles and prepositions, simplified sentence structures, and impaired production of verb inflections ^[1][2]. The specific linguistic features of agrammatism vary across individuals and languages, and its analysis addresses the relationship between grammatical processing, language production, and the neural systems supporting language.
