This study analyzes the linguistic characteristics of the 2020 anti-smoking public service advertisement series 'Nodam'. The 2020 Nodam advertisements consist of three stories. The first story comprises three independent texts in an interview format, but they are unified into a single text through a repeated ‘question-answer' structure and recurring slogans. The second story is a single text woven from the relay-style narratives of five individuals, with independent subtexts bound together by cohesive devices. The third story has a single text structure consisting of one main text and a slogan. In terms of meaning construction, the first and second stories expand the advertisement's meaning and reinforce its purpose by linking subtexts through the same message and cohesive devices. The third story addresses e-cigarettes and smoking students, broadening the target and scope of the anti-smoking message. Additionally, as the advertisements target teenagers, they use abbreviations, neologisms, trendy expressions, and loanwords to capture teenagers' interest and elicit their empathy and participation.
