This research delved deep into the complex and intricate world of derivational verbs in the Indonesian language, with a meticulous analysis of their structure and formation using the lens of derivational morphology. The study scrutinized the systematic rules governing the creation of verbs in Indonesian, exploring the prefixes, suffixes, and root words that significantly shaped their meaning and function. Through advanced linguistic methodologies and extensive data collection, this research aimed to unveil the underlying patterns and principles governing the formation of derivational verbs in Indonesian. The study delved into the intricate web of Indonesian derivational verbs, examining how certain affixes or combinations of affixes could change the meaning of the root word and create an entirely new word. The findings showed that (1) Indonesian verb derivation used a wide range of affixes; these affixes came in various forms, including prefixes like {me(N)-}, {ber-}, {ter-}, and suffixes like {-kan}, {-i}; (2) the use of different affixes with root words resulted in significant semantic shifts, and (3) the significance of affixation patterns and semantic shifts in Indonesian verb derivation was highlighted, which could be used to develop a structured theoretical framework for future linguistic inquiries. The findings of this research offered valuable insights into the language's intricate derivational system, shedding light on the nuanced processes that contributed to the rich tapestry of Indonesian vocabulary. It contributed to a better understanding of the language's syntax, grammar, and partial linguistic structure.

Prophetic, which initially only targeted literary works, developed into an attitude for other domains, including aspects of life. The virtue of prophetic itself is the attitude of humans who must work together to build a better life, fight against things that kill the essence of a human being, and strengthen faith in Allah SWT. Buya Hamka is a figure whose life should be used as a role model because his life has provided many good things for other humans. In relation to prophetic values, this research aims to reveal how the character Buya Hamka in the biographical novel actualizes prophetic values in his daily life. This research is qualitative research using content analysis techniques. The data source in this research is the novel Buya Hamka: A Biographical Novel written by Ahmad Fuadi. The data for this research are novel texts that reflect the actualization of Buya Hamka's prophetic values. The research results show that this novel shows the figure of Buya Hamka who actualizes his prophetic values with the same goal, namely to educate society so that it can escape adversity, oppression and the grip of the colonialists. To realize this goal, Buya Hamka took several steps that were relevant to his background and skills.
