First Person: 나 vs 저 (I / me — plain vs humble) | Korean Grammar

English hands you one socially neutral word for yourself: I. You use it with your best friend, your boss, a police officer, and a toddler, and it never changes. Korean gives you two first-person pronouns, and the split has nothing to do with grammar and everything to do with politeness: 나 (na) is the plain, intimate "I," and 저 (jeo) is the humble, polite "I." Every single time you refer to yourself in Korean, you are quietly choosing a social stance. Pick wrong and you sound either cold and stiff (저 with a close friend) or presumptuous and rude (나 with your boss). This is one of the very first things Korean asks you to get right.

The split: 저 humbles you; 나 is intimate

Use 저 with strangers, elders, superiors, customers, teachers — anyone you address with polite endings (해요체 or 합니다체). Use 나 in 반말, the intimate style, with close friends, younger people, and people you've explicitly agreed to speak casually with.

저는 한국어를 배우고 있어요.

jeoneun hangugeoreul baeugo isseoyo

I'm learning Korean. (polite — 저)

나는 그냥 집에 있을래.

naneun geunyang jibe isseullae

I'll just stay home. (casual 반말 — 나)

Crucially, 저 lowers you relative to the listener — it's a humbling word. It doesn't raise the other person (that's a separate mechanism, done with honorific verb endings); it self-lowers. Because self-lowering is the polite move with anyone above or unknown to you, 저 is the safe default whenever you're in doubt. If you'd address someone with -요, refer to yourself with 저.

💡

저 pairs with polite endings (저는… 해요/합니다); 나 pairs with 반말 (나는… 해). Mixing them — 저 with a casual ending, or 나 with a formal one — is a register clash that sounds off. Choose the pronoun and the ending as a matched set.

The irregular subject form: 내가 / 제가 (never ×나가, ×저가)

This is the error that marks a beginner instantly. When the subject particle 가 attaches, the vowel of the pronoun changes: 나 → 내가, 저 → 제가. You cannot say ×나가 or ×저가 — the forms are suppletive, and you must memorize 내가 and 제가 as fixed units.

제가 할게요.

jega halgeyo

I'll do it. (polite — volunteering)

내가 먼저 갈게.

naega meonjeo galge

I'll go first. (casual)

So "I did it" as a subject is 제가 했어요 / 내가 했어 — never ×저가 했어요, never ×나가 했어. The moment you want "I" as the grammatical subject with 가, reach for 내가 or 제가.

Possessives contract the same way: 내 / 제

The possessive follows the identical vowel shift. Full 나의 → 내, 저의 → 제. In real Korean, the contracted 내/제 is the everyday form; the full 나의/저의 is bookish and literary — you'll meet 나의 in song lyrics and formal prose, but you say 내.

제 이름은 지훈이에요.

je ireumeun jihun-ieyo

My name is Jihun. (polite)

내 방 좀 봐 줄래?

nae bang jom bwa jullae

Can you take a look at my room? (casual)

💡

Heads-up for later: 내 ("my") and 네 ("your," from 너) have merged in pronunciation for most speakers, so people say and text 네 as 니 to keep them apart. That's a second-person issue — see 너 / 당신 — but it's why 내 vs 네 can sound identical in speech.

The object form is regular: 나를 / 저를

Only the subject (가) and possessive trigger the vowel change. With the object particle 를 — and with most other particles — the pronoun keeps its plain shape: 나를/저를, 나한테/저한테, 나랑/저랑.

부장님이 저를 부르셨어요.

bujangnimi jeoreul bureusyeosseoyo

The manager called me. (polite — humble 저 for myself)

왜 나를 안 믿어?

wae nareul an mideo

Why don't you believe me? (casual)

The full paradigm

Slot	Plain (나)	Humble (저)
Topic (은/는)	나는	저는
Subject (가) — irregular	내가	제가
Object (를)	나를	저를
Possessive (의 → contracted)	내 (나의)	제 (저의)
Dative (한테/에게)	나한테	저한테
"and/with" (랑/하고)	나랑, 나하고	저랑, 저하고

For the plural "we" (우리 vs the humble 저희), which follows the same politeness logic, see 우리 / 저희. For the wider family of humble self-reference (저희, 제, 드리다, etc.), see humble 저 / 저희. And remember Korean loves to drop the first-person pronoun entirely when context is clear — see pronoun dropping — so 저/나 appear far less often than English "I."

One homograph to keep straight: 저 the pronoun vs 저 "that yonder"

The syllable 저 does double duty. As a pronoun it means "I (humble)"; as a demonstrative it means "that … over there" (저 사람 = "that person"). Context sorts them out cleanly: 저 sitting before a noun is the demonstrative (저 집, 저 사람), while 저 standing alone or carrying 는/가/를/의 is the pronoun. And the everyday attention-getter 저기요 ("excuse me") uses the demonstrative 저, not the pronoun.

저 사람 누구예요?

jeo saram nuguyeyo

Who is that person (over there)? (저 = demonstrative)

Common Mistakes

1. Saying ×나가 / ×저가 for "I" as subject. The vowel must change with 가.

✅ 제가 갈게요.

jega galgeyo

I'll go. (polite — never ×저가; casual is 내가 갈게, never ×나가)

2. Using intimate 나 with a boss, customer, or stranger. It reads as overfamiliar and rude. Default to 저.

✅ 저는 못 갈 것 같아요.

jeoneun mot gal geot gatayo

I don't think I can make it. (to a superior — 저, not 나)

3. Clashing the pronoun with the register of the ending. 저 goes with polite endings, 나 with 반말. Don't cross them.

✅ 저는 안 가요. / 나는 안 가.

jeoneun an gayo / naneun an ga

I'm not going. (pick one register: polite 저…요, or casual 나…해)

4. Over-using 나의 / 저의 where 내 / 제 is natural. The full 나의 sounds bookish and literary; in everyday speech and writing it contracts.

✅ 이거 제 책이에요.

igeo je chaegieyo

This is my book. (제, not the bookish 저의)

Key Takeaways

Korean has two words for "I," split by politeness: 나 (plain, 반말) and 저 (humble, polite). 저 self-lowers — the safe default with anyone you'd address politely.
Match the pronoun to the ending: 저 … 해요/합니다, 나 … 해.
The subject form is irregular: 나 → 내가, 저 → 제가. Never ×나가, ×저가.
Possessives contract the same way: 내 / 제 (full 나의/저의 is bookish). Objects stay regular: 나를 / 저를.
The pronoun 저 ("I") and the demonstrative 저 ("that over there") are homographs, told apart by position.
