Which of the following is NOT considered a language disorder?

Language fluency disorder, commonly associated with stuttering or other fluency issues, is primarily classified as a speech disorder rather than a language disorder. While it impacts how a person speaks, it does not specifically involve difficulties with the content or form of language, which are key elements of language disorders. Language disorders, such as expressive and receptive language disorders, involve challenges with vocabulary, grammar, and the ability to understand or produce language effectively. Cognitive-communication disorders are characterized by deficits in the cognitive processes underlying communication, which also fall under the umbrella of language impairments. Thus, language fluency disorder stands apart as primarily related to fluency in speech, distinguishing it from the other options that are all recognized as language disorders.
