The Address Finder answers one question: what is a sensible way to get this person’s attention in the situation you described? It weighs the speaker, relative age, relationship, closeness, role, and setting. It does not decide the sentence ending you should use; the Speech Level Finder handles that separate choice.
COMPARE
Older close friend
A woman speaking privately to an older male friend after they have mutually become close.
오빠 (oppa) may fit.The term reflects the speaker’s gender, the other person’s gender, relative age, and an established close relationship—not age alone.
COMPARE
Older manager
The same person is your team leader during a work meeting.
팀장님 (timjangnim) is usually the stronger starting point.An organizational role can outweigh a kinship-style social term in the workplace.
REAL DIALOGUE
First question to a teacher
선생님 supplies the address term; 있어요 keeps the sentence politely conversational.
선생님, 질문이 있어요.Seonsaengnim, jilmun-i isseoyo.Teacher, I have a question.
COMMON MISTAKES
- Treating oppa, unnie, hyung, or noona as a generic word for any older person.
- Attaching -ssi to a family name alone as if it were always equivalent to Mr. or Ms.
- Choosing from age while ignoring a clear workplace, school, or service role.
USE WITH CARE
If no established title is clear, you do not always need to force one. A polite greeting or question without a direct address term can be the least presumptive opening.
