dysphasia

This term describes a specific impairment of language processing, often manifesting as a struggle to retrieve words or comprehend spoken input. It carries a clinical, medical connotation and is typically used in neurological or speech-therapy contexts to describe a deficit rather than a total loss of function.

Because it refers to a medical condition or a state of impairment, it is treated as an uncountable noun. It does not take a plural form in standard medical discourse, and one does not refer to multiple dysphasias; instead, clinicians discuss the severity or the specific type of the condition.
