Which communication disorder is characterized by difficulty in swallowing?

Dysphagia is the correct choice because it specifically refers to a condition where an individual experiences difficulty swallowing. This can manifest as trouble with food or liquid moving from the mouth to the stomach, leading to challenges in eating and drinking safely. Dysphagia can result from various underlying issues, including neurological conditions, structural abnormalities, or other medical problems.

In contrast, dysarthria is a motor speech disorder that affects the physical production of speech, making it difficult for a person to articulate words clearly. Aphasia is a language disorder that affects verbal communication and can impact speaking, understanding, reading, and writing, but does not specifically involve swallowing function. Stuttering is a speech fluency disorder characterized by disruptions in the flow of speech, such as repetitions or prolongations of sounds and words, but it does not relate to swallowing difficulties. Hence, dysphagia is the term that directly addresses the issue of swallowing difficulties within the context of communication disorders.
