What does phonology refer to in language?

Phonology is a linguistic term that specifically refers to the rules governing the sound system of a language. This includes how speech sounds function and combine to create meaning within that language. It encompasses aspects such as phonemes (the smallest units of sound), syllable structure, stress patterns, and intonation. Understanding phonology is crucial for language development, especially in early childhood education, as it helps children recognize the sounds that form words and how these sounds interact within their language, ultimately aiding in reading and writing skills. Hence, this choice accurately represents the essence of phonology in linguistic study.
