Suppletive Honorific Verbs: 계시다, 드시다, 주무시다, 돌아가시다

For most verbs, honorifying the subject is mechanical: add -(으)시-. 가다 → 가세요, 읽다 → 읽으세요, done. But a small, high-frequency set refuses this rule. To honorify "eat," "sleep," "be present," or "die," Korean throws the regular verb away and reaches for a completely different word. These are the suppletive honorifics — and because there is no rule that generates them, they are pure memorization, exactly like English go → went.

The set is small (six or seven items matter), but they are among the most-used verbs in the language, so the payoff for learning them is immediate. Get them wrong and you produce forms like ×먹으세요 for an elder — grammatically shaped but socially tone-deaf, the equivalent of telling your grandmother to "feed."

The core set

Each already contains 시, so you conjugate them like any -시- verb: present -세요, past -셨어요, formal -십니다. They just start from an irregular stem.

드시다 / 잡수시다 — eat and drink

드시다 covers both 먹다 "eat" and 마시다 "drink" — one honorific word for two plain ones. In everyday polite speech it is the workhorse.

For a still-higher register — addressing the very elderly, or in formal hosting — there is 잡수시다, and the invitation 잡수세요 / 어서 잡수세요 "please, do help yourself." It sounds warm and traditional, common from a host to an honored guest.

Notice 진지 in the first example: it is the honorific noun for 밥 "rice / meal." Suppletive honorific verbs travel with honorific noun partners, and using the plain noun with the honorific verb sounds half-dressed. More on this below.

주무시다 — sleep

자다 "sleep" has no -(으)시- form in careful speech; the honorific is 주무시다. Its most-heard shape is the bedtime farewell 안녕히 주무세요 "good night" (said to someone you respect).

계시다 — be present / stay

계시다 is the honorific of 있다 when 있다 means "to be located / stay / be present." It is how you say an elder is somewhere.

There is a subtlety here that trips up even advanced learners: 계시다 is only for the person themselves existing. When it is a person's possession or attribute that exists — "you have a question," "do you have time" — Korean switches to 있으시다 instead. That split is important enough to have its own page: 계시다 vs 있으시다.

돌아가시다 — pass away

돌아가시다 literally means "to go back / return," used as the respectful way to say someone died. The plain 죽다 with an honorific ending (×죽으시다) is jarring; for any elder or respected person, 돌아가시다 is the only natural choice.

말씀하시다 — speak

말하다 "speak / say" honorifies as 말씀하시다, built on 말씀, the honorific noun for 말 "words / speech."

말씀 is a two-way word — it also humbles your own speech ("제가 말씀드릴게요" = "let me tell you," lowering yourself). The honorific-subject use is the one on this page; the humbling use pairs with the benefactive -아/어 드리다.

편찮으시다 / 시장하시다 — be ill, be hungry

편찮으시다 honorifies 아프다 "be ill," but with a scope limit: it describes the whole person being unwell. When it's a specific body part that hurts, Korean uses ordinary 아프다 + -(으)시- (아프세요) instead — another instance of the direct-vs-indirect split. 시장하시다 is the somewhat formal honorific of 배고프다 "be hungry."

Honorific nouns travel with them

Suppletive honorific verbs have honorific noun partners, and native speakers pair them. Using a plain noun as the object while the verb is honorific reads as inconsistent.

How this differs from English

English also has "elevated" vocabulary — pass away for die, dine for eat, reside for live — but choosing them is stylistic and optional; "my grandfather died last year" is perfectly acceptable and respectful. In Korean the suppletive honorific is grammatically obligatory once the subject outranks you: you cannot decline to use 돌아가시다 or 드시다 without sounding cold or rude. The other difference is scale — English elevated words are scattered and register-neutral in the past; Korean's suppletives are a tight, closed list that you can and must memorize as a unit, like a small irregular-verb table.

Common Mistakes

1. Regularizing 먹다 into ×먹으세요. For anyone you respect, "eat" is 드세요 (or 잡수세요), never the regular honorific of 먹다.

2. Using 자세요 instead of 주무세요 for "sleep." 자다 + -시- is not the honorific; the suppletive 주무시다 is.

3. Saying ×죽으셨어요 for a person's death. Death of a respected person is 돌아가시다.

4. Mixing registers with ×먹으시겠어요. Once you're in honorific register, the eat-verb itself must be suppletive; you can't honorify 먹다 and keep it.

5. Pairing an honorific verb with a plain noun. 드시다 wants 진지, not 밥, when the subject is honored.

Key Takeaways

• A closed set of verbs replaces the stem instead of adding -(으)시-: 먹다→드시다, 자다→주무시다, 있다→계시다, 죽다→돌아가시다, 말하다→말씀하시다, 아프다→편찮으시다, 배고프다→시장하시다.
• They conjugate normally once you have the stem: 드세요, 드셨어요, 드십니다.
• 잡수시다 is a higher-register "eat"; 돌아가시다 is a euphemism, so no extra softening is needed.
• Honorific verbs pair with honorific nouns: 진지, 연세, 성함, 댁, 말씀.
• 계시다 (person present) vs 있으시다 (possession/attribute) is a distinct split with its own page.
