-ssi, -nim and -ya: Korean Honorifics Without the Confusion
Korean honorifics like -ssi (씨), -nim (님) and -ya (야) show respect and closeness. Learn which one to use for coworkers, teachers, bosses and close friends.
By a native Korean teacher · · 3 min read
Watch a K-drama for ten minutes and you will hear names with small endings attached: Minsu-ssi, sajang-nim, Jiwon-ah. These endings are Korean honorifics, and they tell everyone in the room how you see the other person. Use -ssi (씨) for polite, neutral address, -nim (님) for people you must honor, and -ya or -ah (야/아) only for friends and people younger than you.
Word at a glance
씨 / 님 / 야ssi / nim / ya
- Literally
- Mr./Ms. suffix, honored-person suffix, friendly calling suffix
- In natural English
- name endings that show how much respect or closeness you feel
-ssi (씨): the polite default
씨 (ssi) is the closest thing Korean has to "Mr." or "Ms.," but it is attached to a full name or a first name, never to a family name alone. You will hear it between coworkers of similar rank, and when adults meet for the first time.
There is one catch. Using -ssi toward someone clearly above you, such as your boss, can sound cold or even rude. It is also unusual to use it with a title you already have for the person. Think of it as polite but level: you treat the other person as an equal.
민수 씨, 이 자료 좀 봐 주세요.
Minsu ssi, i jaryo jom bwa juseyo.
Minsu, could you take a look at this material?
김지원 씨 맞으세요?
Gim Jiwon ssi majeuseyo?
Are you Ms. Kim Jiwon?
-nim (님): for people you honor
님 (nim) lifts the person up. It attaches to job titles and roles: 선생님 (seonsaengnim, teacher), 사장님 (sajangnim, company president or shop owner), 교수님 (gyosunim, professor). In Korea you rarely call a teacher by name. You say the role plus -nim.
Customers are also honored this way. A shop staff member will call you 고객님 (gogaengnim, dear customer). Online, 님 is also often added to usernames, which is why you see it in comment sections.
- 선생님 (seonsaengnim): teacher, and also a respectful way to address a doctor or an expert
- 부장님 (bujangnim): department head at a company
- 사장님 (sajangnim): boss, owner, and the friendly word customers use for shopkeepers
- 고객님 (gogaengnim): customer, used by staff
-ya and -ah (야/아): the close-friend call
When you call a friend, a younger sibling or a child, you attach 아 (a) to a name ending in a consonant and 야 (ya) to a name ending in a vowel. Jiwon becomes Jiwon-ah, Minsu becomes Minsu-ya. Fans often write -ah for both forms.
This is a calling form only. It works when you are speaking to the person, and it signals warmth. Never use it for someone older or for a stranger, because it treats them as a child.

Jiwon, have you eaten?

Minsuya, ppalli wa!
Minsu, come quick!
Which one should you use?
Ask two questions: is the person older or higher than me, and how well do I know them? If the answer is older and higher, use their title plus -nim. If the person is a peer or a new acquaintance, -ssi is safe. If they are a close friend your age or younger, drop the honorific and use -ya or -ah once you are comfortable.
Korean also has other address words, such as oppa, unnie, hyung and noona, which replace names entirely among people close in age. When in doubt, ask. Koreans will happily tell you how to address them, and the question itself shows respect.
Questions people ask
Can I call someone just by their name in Korean?+
Only if you are close and of similar age, or the person is younger. Otherwise add -ssi, or use their title with -nim.
Is -ssi rude?+
No, it is polite between equals. It becomes rude when used toward a boss or an elder, who expect a title plus -nim.
Should I put -ssi after a family name only?+
Avoid it. Saying only "Kim-ssi" can sound cold or disrespectful. Use the full name, or the first name, plus -ssi.
Do fans use -nim for idols?+
Sometimes. Fan accounts and formal messages may add 님 to a name or title to sound respectful, while casual chat often uses nicknames.
Do foreigners need to use honorifics?+
Koreans do not expect perfect use, but trying shows effort. Starting with -ssi and titles plus -nim covers most situations.
