In language study, which term describes the science that analyzes sound systems and patterns?

• A. Phonology
• B. Semantics
• C. Morphology
• D. Syntax

Answer: (A)

Phonology is the study of how sounds function in a language—the sound system, the set of distinct sounds (phonemes), and the rules that govern how those sounds combine and pattern with one another. It explains why certain sound sequences are possible or not, how sounds can shift in different environments (for example, how a sound may be pronounced differently without changing meaning), and how those sound patterns help distinguish words. This focus on sounds and their organizational rules differentiates it from semantics, which deals with meaning; morphology, which looks at the structure of words; and syntax, which examines how words form phrases and sentences. For instance, the way English uses a contrast between /p/ and /b/ to differentiate words like pat and bat is a clear example of phonology at work. So, the science that analyzes sound systems and patterns is phonology.
