#86: How Korean Talks About Age - And Why It Changes Everything

Age in Korean is not just a number - it is the foundation of how every conversation is structured. In this episode of TOPIK & Beyond, host Eliza explains the age-based speech system that shapes all Korean social interaction: how to count and express age correctly (살 vs 세), the relational titles that replace names (언니, 오빠, 형, 누나, 선배, 후배), and the speech level system (반말 vs 존댓말) that adjusts based on age and relationship.

Anchored in an anonymous student story about a conversation that suddenly shifted after age was revealed, this episode teaches 13 Korean words and expressions - including a short A2–B1 Korean story segment. It explains not just the vocabulary but the cultural logic of 위계질서 (hierarchy) that makes Korean age-consciousness one of the most important things for any learner to understand.
