Which of the following is an example of a language disorder?

Aphasia is classified as a language disorder because it specifically impacts a person's ability to understand and produce language, which includes both spoken and written forms. This condition often arises from brain injuries, strokes, or neurological diseases, affecting areas of the brain that are responsible for language processing. Individuals with aphasia may struggle to find words, construct sentences, or comprehend spoken language, highlighting the disorder’s direct relationship to language capabilities.

In contrast, stuttering primarily affects the fluency of speech rather than language itself, making it a speech disorder. Apraxia is a motor speech disorder that involves difficulty planning and coordinating the movements required for speech, while dysarthria involves weakened muscle control impacting the clarity of speech. Both apraxia and dysarthria are related to speech production rather than the broader language skills, thus distinguishing them from aphasia, which specifically targets language processing and communication.
