Phonological
Phonological refers to the study of the sounds of a language, including how they are produced, perceived, and organized within a particular linguistic system. It involves analyzing the phonetic features of speech sounds, such as their articulation, duration, and frequency, as well as their patterns and rules in relation to each other in a given language. Phonological analysis also examines how sounds can change or interact with each other in different linguistic contexts, leading to variations in pronunciation and meaning.
