Which term refers to the branch that analyzes how phonemes function to distinguish meaning in a language?

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

Answer: (B)

Understanding how phonemes function to distinguish meaning centers on phonology. This field treats phonemes as abstract units whose contrasts create differences in meaning across words. It investigates which sound differences actually matter in a language—often demonstrated with minimal pairs like “pat” vs. “bat”—to show how a single phoneme change can flip meaning. Phonology also looks at the rules governing sound patterns, such as where certain sounds can occur (phonotactics) and how a single phoneme can surface as different real‑world sounds in various contexts (allophones) without changing meaning. This focus on how sound systems encode meaning sets phonology apart from phonetics, which studies the physical properties and articulation of speech sounds, and from articulation, which concerns how the speech organs produce those sounds.
