Phonological disorder: Which term describes impairment in comprehension of the sound system and the rules governing sound combinations?

• A. Phonology
• B. Phonetics
• C. Articulation
• D. Phonological Disorder

Answer: (D)

Understanding the sound system and the rules for how sounds can be combined is phonology—the knowledge of how sounds function in a language. When there’s an impairment in comprehending and applying that system and its rules, the difficulty is described as a phonological disorder. This focuses on the mental representations and rule-based use of sounds, not just the physical production of individual sounds. In contrast, articulation concerns how speech sounds are actually produced by the organs, and phonetics is the study of the physical properties of those sounds. So describing an impairment in understanding and using the sound system points to a phonological disorder.
