Language disorders or language impairments are disorders that involve the processing of linguistic information. Problems that may be experienced can involve grammar (syntax and/or morphology), semantics (meaning), or other aspects of language. These problems may be receptive (involving impaired language comprehension), expressive (involving language production), or a combination of both. Examples include specific language impairment and aphasia, among others. Language disorders can affect both spoken and written language, and can also affect sign language; typically, all forms of language will be impaired.
Note that these are distinct from speech disorders, which involve difficulty with the act of speech production, but not with language.
Psychopathology of language
A special class of language disorders is studied by the psychopathology of language. Its topics of interest range from simple speech error to dream speech and schizophasia.
