<![CDATA[This literature review examines semantic transformation processes in Indonesian slang through comprehensive analysis of morphological and semantic change mechanisms operating within informal language varieties. The study employs qualitative library research methodology to synthesize existing scholarship on Indonesian slang evolution, focusing on the complex interplay between morphological innovation, semantic change, and sociolinguistic factors in contemporary digital communication contexts. Analysis reveals that Indonesian slang employs sophisticated morphological processes including clipping, blending, innovative affixation, metaphorical compounding, and creative acronym formation that extend beyond traditional word formation mechanisms documented in formal Indonesian grammar. Social media environments serve as primary catalysts for linguistic innovation, creating unprecedented opportunities for rapid morphological experimentation and semantic evolution through viral dissemination, algorithmic mediation, and real-time community feedback. Generational differences emerge as crucial factors influencing innovation patterns, with Generation Z speakers demonstrating distinct preferences for morphological processes that integrate global digital culture references with Indonesian phonological structures. Digital communication platforms fundamentally transform the temporal dynamics of language change, compressing traditional timescales and enabling rapid cycles of innovation, adoption, and obsolescence. The findings suggest that contemporary Indonesian slang operates according to distinct morphological and semantic principles that require new analytical frameworks integrating insights from cognitive linguistics, sociolinguistics, and digital communication theory. This review establishes comprehensive research priorities for future empirical investigation, emphasizing the need for longitudinal studies, regional variation analysis, and hybrid computational-qualitative methodologies to advance theoretical understanding of rapid language change in globalized digital communication environments.]]>
