Titles & Jobs as Address: 사장님 / 부장님 / 교수님 and 씨 vs 님

In an English-speaking office you can call the intern, your manager, and the CEO all by their first names and simply lean on tone to carry the respect. Korean does not give you that option. The word you use to name a person is itself a ranked act of respect, and at work the ranking is spelled out on their business card: you address people by their 직함 (職銜, job title) plus the honorific suffix 님, almost never by their bare name. Learning this is not etiquette trivia — it is grammar, because the suffix you attach (씨 or 님) is selected by where the person stands relative to you.

The core forms: job title + 님

A Korean company is a ladder of titles, and each title becomes a term of address the moment you add 님. You do not say "excuse me, Mr. Kim" to your department head — you say 부장님, "department-head-sir." The title is the name.

The everyday rungs, roughly bottom to top:

Outside the company ladder, the same pattern covers other institutions: 교수님 (professor, 敎授), 원장님 (director of a clinic or academy), 대표님 (CEO/representative), 기사님 (a driver or technician), 사모님 (the boss's wife, or a respectful "madam").

Notice that these titles double as address (calling out to the person) and as a third-person label. You refer to your absent boss the same way:

Adding a surname for clarity: 김 부장님

When one title is shared by several people — a company can have many 과장 — you disambiguate by prefixing the surname: 김 부장님, 이 교수님, 박 과장님. The order is fixed and worth memorizing: surname → title → 님. This is the Korean equivalent of "Mr. Kim," except that the "Mr." slot is filled by the person's actual rank.

This is exactly where English speakers stumble. English "Mr. Kim" maps the surname to a generic honorific ("Mr."). Korean has no generic honorific to plug a stranger's name into at work — it plugs in the rank instead. There is no natural way to say "Mr. Kim" to your boss; you say 김 부장님, and the sentence itself now encodes that this Kim outranks you.

씨 vs 님: rank selects the suffix

Below the title-plus-님 layer sits the pair every learner has to sort out: 씨 versus 님. Both attach to how you name a person, but they sit at different heights.

• 씨 attaches to a name (민수 씨, 김민수 씨) and marks level, polite respect — for peers, colleagues, classmates, people at a mild social distance. It looks across, not up.
• 님 attaches to titles and roles (부장님, 고객님) and looks up — it elevates a senior, a customer, a member.

So the person's rank literally chooses the suffix for you. A colleague at your level is 민수 씨; the moment that colleague is promoted over you, 민수 씨 curdles into something too flat, and you switch to their title + 님.

One trap: 씨 is polite only on a given name or full name. On a bare surname — 김 씨, 이 씨 — it turns curt, even demeaning, the tone a foreman might use barking a laborer's family name. If all you have is the surname and the person outranks you, you must go up to title + 님, never down to surname + 씨.

선생님: respect, not a claim about teaching

선생님 (先生, literally "one born before / teacher") is the Swiss-army address term. Yes, it means "teacher," and you use it for actual teachers. But its far more common life is as the default respectful way to address any adult you have no other title for — a stranger whose job you don't know, an older customer, a doctor, someone at a service desk. Calling a shopkeeper 선생님 is not claiming they teach anything; it is simply the safe, deferential "sir/ma'am."

For learners this is a lifeline: when you are unsure how to address a respectable adult, 선생님 is almost never wrong. And to flag a stranger before you have any address term at all, the neutral opener is 저기요 ("excuse me / over here").

Korean also leans heavily on kinship terms for strangers — 이모 ("auntie") to a restaurant ajumma, 사장님 to almost any small-shop owner. Those are covered in kinship as address. And the deeper reason all of this feels non-negotiable — why there is no neutral "hey you" — is the subject of why honorifics exist.

Common Mistakes

1. Using a bare name or name + 씨 for a superior. 씨 is horizontal; on a boss it flattens the hierarchy and sounds presumptuous.

2. Addressing a superior by their (given) name. Calling your boss 철수야 or even 철수 씨 is close to unthinkable; the name disappears entirely behind the title.

3. Dropping 님 from a title. A bare 교수 or 사장 is the rank as a noun, not a way to speak to the person; it lands as blunt, almost rude.

4. Stacking 씨 onto a title, or 씨 onto a bare surname. 씨 goes on names, not titles (a title already carries 님), and never on a lone family name.

Key Takeaways

• At work you address people by job title + 님 (부장님, 과장님, 교수님), not by name; the title is the address.
• Disambiguate shared titles with surname + title + 님 (김 부장님) — this is Korean's "Mr. Kim," with the rank filling the "Mr." slot.
• 씨 (on a name) is level respect for peers; 님 (on a title/role) looks up to superiors. Rank selects the suffix — reaching one rung too low for a boss is the classic error.
• 씨 is polite only on a given or full name; on a bare surname (김 씨) it turns curt.
• 선생님 is the all-purpose respectful address for any adult you have no title for — a claim of respect, not that they teach.
