Effective communication is critical in our daily interactions, enabling individuals to comprehend and evaluate their actions within diverse contexts. This paper explores the impact of evolving language—particularly the emergence of new slang and established expressions unique to specific generational cohorts—on intercultural communication. The integration of these terms into everyday discourse can create barriers for those unfamiliar with them, leading to potential misunderstandings between generations created by for e.g.: Millennials, Gen Z, and Gen Alpha. This phenomenon poses significant challenges as the rapid evolution of language within social media platforms like Instagram and TikTok fosters a dynamic yet complex communicative landscape. The research uses data from the corpus News on the Web (NOW) to analyze trends in intergenerational communication, assessing the frequency and context of newly coined terms and phrases over recent years. By investigating these trends, the paper highlights the necessity for greater awareness and understanding of contemporary language, emphasizing their role in fostering effective communication across generational divides.
