Whether the search engines turn up much on phonology apart from the Rutgers Optimality Archive and entries on websites at American universities which tell you about courses on phonology, I don't know. I haven't checked. These pages are meant to fill the gap by explaining what phonology is all about. More details can be found in standard textbooks. There is a list of references to these at the bottom of the page on Rules and Derivations . 0.
Phonology is the study of how the sound systems of a language interact with each other.
Thus phonology is the study of how the vowels and consonants interact with each other and how they, in turn, may be affected by elements such as stress. Phonology is divided into two sub-branches. Segmental phonology deals with the behaviour of vowels and consonants. Suprasegmental phonology deals with stress, tone and other prosodic phenomena. My particular field is metrical phonology which comes under the aegis of the latter.
