What does phonology mean?
Phonology is the branch of linguistics concerned with the sound systems of languages. It studies how speech sounds are organized, which sounds distinguish meaning, and how sounds change according to grammatical or contextual factors. A linguist might examine the phonology of English, compare the sound patterns of two languages, or describe the phonology of a regional dialect. The term is especially important in historical linguistics, language teaching, and the study of language change. Unlike general descriptions of pronunciation, phonology looks at patterns and functions within a language rather than treating each sound only as a physical act. Its insights help explain why related languages may develop different forms and why speakers of one language can find another language difficult to hear or learn.
The study of the sound systems of languages, including the functions and relationships of speech sounds.
"She specializes in the phonology of Romance languages."
This is the academic sense and is generally used in linguistics and related fields.
The particular system of sounds used in a language, dialect, or other variety of speech.
"The phonology of the dialect is stable across generations."
This sense describes an individual sound system rather than the academic discipline that studies such systems.
Used when referring to the sound systems of multiple languages, dialects, or varieties.
"The researchers compared the phonologies of several endangered languages."
Phonology reveals that the same sounds can carry different meanings in different languages, making it a key to understanding why some words seem unrelated on the surface.

Where does phonology come from?
The word comes from Greek phōnē, meaning “sound” or “voice,” combined with the suffix -logy, meaning “study of.” Its development reflects the Greek terms phōnētikós, “pertaining to sound,” and phōnētikē, “the science of sounds.” The English word entered scholarly usage through the study of language sounds and became especially associated with the systematic analysis of phonological systems.

How phonology is actually used
In academic contexts, phonology is normally used for the systematic study of language sounds. It is related to but distinct from phonetics, which focuses more directly on the physical articulation and perception of sounds.
Easily confused with phonology
Phonetics describes the physical properties and production of speech sounds, whereas phonology focuses on how sounds function systematically within a language.
