Executive Summary

Unlike English where anyone can be called by their first name, Korean culture uses relational kinship titles even among friends: a female calls an older male "Oppa" and an older female "Unnie", while a male calls an older male "Hyung" and an older female "Noona".

1. The 2x2 Matrix of Kinship Titles

• If YOU are FEMALE: An older male friend is "Oppa" (오빠); an older female friend is "Unnie" (언니).

• If YOU are MALE: An older male friend is "Hyung" (형); an older female friend is "Noona" (누나).

• Crucial Etiquette Tip: Never use these titles with strangers or in formal business settings. In business, always use full names followed by "-ssi" (씨) or professional job titles like "Daeri-nim" or "Gwajang-nim".

💡

Key Takeaway

These kinship titles denote emotional closeness. Allow the older person to suggest using them first.
