Literary theory and linguistic theory can be applied to analyze literary works, which include phonology, morphology, syntax, and lexical studies. Morphology studies word formation, which varies by region and dialect, like Serang dialect of Javanese in "Yuni". In this writing, this novel is the main data source or primary source. The analysis found 89 vocabularies of Serang Javanese language experienced the morphological process of affixation, including 26 vocabularies experienced prefixes (affixes at the beginning of the base word) in the form of ng-, di-, se-, ke-, and nge-, 55 vocabularies experiencing suffixes (affixes at the end of the base word) in the form of -an, -ne, -i, -aken, -e, -ni, and -kaken, 8 vocabularies experiencing confixes (combined affixes) in the form of nge-. .. -aken, ke-...-an, di-...-aken, nge-...-i, se-... -e, ng-...-i, di-...-i, and ng-... -ni and 15 Serang Javanese vocabularies that undergo the morphological process of reduplication, including 1 vocabulary that undergoes dwipurwa reduplication (repetition in the first syllable), 11 vocabularies that undergo the process of dwilingga tansalin swara reduplication (repetition of the basic form is not accompanied by a change in phonemes), and 3 vocabularies that undergo pseudo-phallus reduplication or pseudo-reduplication (pure reword).
