Which term concerns the study of a language's sound system describing the abstract system that allows speakers to distinguish meaning from noise?

• A. Phonology
• B. Phoneme
• C. Polysemy
• D. Prosodic Features

Answer: (A)

Phonology is the study of a language’s sound system and the abstract set of contrasts that let speakers distinguish meaningful words from noise. It examines how sounds function to create meaning, including the rules and patterns that govern which sound combinations are allowed and how different sounds contrast to signal different words. This field focuses on mental representations of sounds and the systematic relationships between them, not on the physical properties of the sounds themselves—that area is phonetics. A phoneme is the smallest unit of sound that can change meaning, so while it’s central to how meaning is distinguished, the question is about the study of the system as a whole, not just the unit. Other terms like polysemy refer to multiple meanings of a word, and prosodic features deal with rhythm, stress, and intonation, which are about how speech is produced and heard rather than the abstract sound system that differentiates words.
