What type of language disorder involves difficulty in forming sounds or coherent sentences?

Expressive language disorders specifically refer to difficulties that individuals experience in expressing their thoughts, ideas, or feelings through speech. This can manifest as challenges in forming recognizable sounds, constructing coherent sentences, or utilizing appropriate vocabulary. A person with an expressive language disorder might know what they want to say, but they struggle to put words together in a way that others can easily understand.

Receptive language disorders, on the other hand, impact a person's ability to understand spoken or written language, which distinguishes them from expressive disorders. Fluency disorders primarily involve issues with the flow of speech, such as stuttering, and voice disorders pertain to problems with pitch, volume, or quality of voice. Hence, expressive language disorders are the most fitting choice for a situation where forming sounds or coherent sentences presents a challenge.
