The Madurese language, which is used by the Madurese ethnic community both on Madura Island and outside the island, has significant dialect diversity. The mobility of the Madurese people and interaction with the Javanese language on the island of Java resulted in a mixture of dialects, which influenced the formation of new vocabulary through morphophonemic processes. This research aims to analyze the affixation process in Madurese, especially the use of the prefixes {-e} and {-pa} in the Sekar Assre’ 4 textbook. In this research, the prefixes {-e} and {-pa} are analyzed based on form, function , and its meaning in the formation of verbs, adjectives and nouns. The research uses a qualitative descriptive approach with listening and listening methods, as well as data analysis techniques such as drop and replace. The research results show that the prefix {-e} and its allomorphs (e-, epa-, eka-) function to form passive verbs and adjectives, while the prefix {pa-} functions to form nouns, especially those related to certain professions or activities . It is hoped that this research can contribute to understanding the morphological structure of the Madurese language, especially related to the role of the prefixes {-e} and {-pa} in everyday communication and in learning Madurese in schools.

Language can be in the form of speech, writing, or sign, and has a structure consisting of vocabulary, grammar, and phonology.

Language as an important means of communication for social interaction, has various aspects that need to be researched, including morphology. In this context, the suffix affixation becomes the main focus, where this process involves the addition of suffixes at the beginning and end of the base word, which is a combination of prefixes and suffixes. The use of suffixes in the Madura language is an important aspect that reflects the richness of language morphology. Research results show that suffixes in the Madura language have significant variations, such as suffixes that function to form verbs, nouns, and adjectives. This research uses a qualitative descriptive approach, which emphasizes more on the presentation of meaning, description, and explanation of data in relevant contexts. In the use of suffix in making short stories in Madura language.
