ABSTRACT

This study examines the semantic shift and sociolinguistic implications of the neologism “young forty,” which has become widely used as of 2025. Initially introduced as a marketing term in 2015, the expression has evolved into a derogatory label used to mock individuals in their forties, with its usage frequency surging sharply in 2025. This study confirms that “young forty” is frequently used as a term rooted in hostility caused by political differences. As fundamental alternatives to address this issue, this study proposes strengthening intergenerational communication and actively using Korean honourifics within online communities.
