This paper explores the significant impact of pop culture on language evolution through the creation of neologisms—new words and expressions that enter common usage. Pop culture, through media such as films, music, television, and social media, not only enriches language but also introduces complexities in communication. Neologisms reflect societal shifts and technological advancements, serving as linguistic markers that encapsulate cultural and social dynamics. While they enhance expressiveness and fill lexical gaps, their emergence can lead to confusion and misunderstandings due to varying degrees of acceptance and understanding across different demographics. This analysis highlights the dual role of neologisms in both enriching linguistic expression and posing challenges to clear communication, underscoring the need for careful integration into mainstream language to avoid potential miscommunications.
