Abstract: The current study entitled “A Morphological Analysis of Slang Words Used by Characters In Ralph Breaks the Internet Movie” aimed to investigate the morphological processes of constructing slang words and its meaning of the found slang words used by the movie characters. This research used a descriptive qualitative method with content analysis design. The findings revealed that there are 42 slang words categorized into different morphological processes included compound (14,28%), clipping (11,90%), blending (14,28%), affixations (16,66%), reduplicative (7,14%), backformation (2,4%), abbreviation (2,4%), conversion (4,76%), alternation (14,28%), extension (4,76%) and word manufacture (7,14%). This study demonstrated the meaning changes of the slang words that have been affected through certain morphological processes by modifying their word category. Consequently, some slang terms have preserved the original meaning despite the changes in their spelling. In the meantime, certain slang words get abbreviated or shortened and retained their original meaning. Meanwhile, some slang words change their meaning by deriving their word category. Besides, there were certain slang words that change their meaning depending on word usage.Key words: morphology, Ralph Breaks the Internet, slangAbstrak.
