In Korea, "성씨" (clan names) refer to the family names that indicate a person's lineage. These names are often derived from geographical locations, historical figures, or specific meanings. Common clan names include 김 (Kim), 이 (Lee), and 박 (Park), which are among the most prevalent in the country. Each clan name is associated with a specific 족보 (genealogy) that traces the family's ancestry. This system helps to identify the family's origin and social status. Clan names play a significant role in Korean culture, influencing social interactions and relationships within communities.
