Phonology is divided into two separate studies, phonetics and phonemics.
The second, third and fourth chapters discuss phonetics, phonemics and distinctive features.
Others therefore suggested renaming the study of language-dependent pronunciation "phonemics" or "phonematics" instead, but this did not gain widespread acceptance either, so the terms "graphemics" and "graphematics" became more frequent.
Phonemics: a technique for reducing languages to writing.
Phonemics studies how the sounds are used.
The unit of analysis for phonemics is called phonemes.
It is in fact a balance among phonemics, morphology, etymology, and grammar; and, like that of most living languages, has its share of inconsistencies and controversial points.
The argument was originally made against a background of structuralist phonemics which equated the two.
