dysgrammatism

Dysgrammatism is a language disorder characterized by marked delays in language development, specifically an inability to learn grammar and syntax rules at the typical age. This condition is often a sign of inherited language disability but can also indicate intellectual disability or other forms of brain damage. It is distinct from dysarthria, which is a motor speech disorder resulting from neurological damage affecting the muscles used for speech production. Dysarthria can cause slurred, slow, or inaudible speech and may affect articulation, phonation, and respiration.12
