Fast vs Early in Korean: 빨리 vs 일찍, 빠르다 vs 늦다

Quick answer: 빨리 (ppalli) means "quickly" — it's about speed. 일찍 (iljjik) means "early" — it's about where you are on the clock. So 빨리 오세요 means "hurry up and get here," while 일찍 오세요 means "come at an early hour." The same split runs through the adjectives: 빠르다 and 느리다 describe speed, 이르다 and 늦다 describe timing.

English lets one word do both jobs. "You're early" and "that was fast" feel like cousins, and "he's slow" can mean either a slow walker or a person who shows up after everyone else. Korean keeps those two ideas in separate boxes, and mixing them up is one of the fastest ways to sound like a learner. The good news: once you see the split, it's almost impossible to unsee.

The two boxes

One note on conjugation before we go further: 빠르다 and 이르다 are 르 irregulars, so they become 빨라요 and 일러요. 느리다 is regular (느려요), and 늦다 is a plain descriptive verb (늦어요).

빠르다: how fast something moves

Use 빠르다 when something covers ground — real or figurative — in a short time.

• 한국 인터넷은 정말 빨라요. — Korean internet is really fast.
• 말이 너무 빨라요. 조금만 천천히 말해 주세요. — You speak too fast. Please speak a little more slowly.
• 제 시계는 5분 빨라요. — My watch is five minutes fast.

That last one is worth memorizing, because it's the one place where English and Korean agree perfectly: a watch that runs ahead is 빠르다, and a watch that lags is 느리다 — never 늦다.

빠르다 also stretches to mean "sooner than expected," which is where learners start to wobble:

• 벌써 도착했어요? 빠르네요! — You're here already? That was fast!
• 생각보다 빨리 끝났어요. — It finished sooner than I thought.

Notice that in both cases the feeling is still speed: a short amount of time passed. If you want to say the thing happened at an early hour, that's 일찍 or 이르다.

일찍 and 이르다: where you are on the clock

일찍 is the adverb you want for "early" in daily life. It pairs with waking up, going to bed, arriving, leaving.

• 오늘은 일찍 자려고요. — I'm planning to go to bed early today.
• 내일 일찍 일어나야 해요. — I have to get up early tomorrow.
• 죄송한데 오늘 좀 일찍 가도 될까요? — Sorry, would it be okay if I left a bit early today?

That last sentence is pure survival Korean in a workplace — and if you need the longer version, there's a whole set of phrases for slipping out of a work dinner early.

이르다 is the adjective, and it carries a small extra flavor: earlier than it ought to be.

• 아직 이른 시간이에요. — It's still early. (The hour hasn't arrived yet.)
• 9시 회의요? 조금 이른데요. — A 9 o'clock meeting? That's a little early.
• 포기하기엔 아직 일러요. — It's still too early to give up.

That third pattern — -기엔 아직 일러요 — is how Koreans say "it's too soon to say." 빠르다 does not work there. 포기하기엔 아직 빨라요 sounds like you're describing the speed of your giving up, which is not the thought you had.

늦다 vs 느리다: the mistake that gives you away

This is the pair worth getting right today.

늦다 = behind the time something was supposed to happen.

• 늦어서 죄송합니다. — Sorry I'm late.
• 버스가 늦게 와서 지각했어요. — The bus came late, so I was late for work.
• 오늘 좀 늦을 것 같아요. — I think I'll be a bit late today.

느리다 = moving at a low speed.

• 할머니는 걸음이 느리세요. — My grandmother walks slowly. (Literally: her steps are slow.)
• 와이파이가 너무 느려요. — The Wi-Fi is so slow.
• 제 시계가 10분 느려요. — My watch is ten minutes slow.

If you text a friend 느렸어요 meaning "I was late," they will picture you crawling down the street. The word they need is 늦었어요. And if you say 늦게 걸어요 meaning "I walk slowly," it sounds like you walk at night, or that you start walking after everyone else. Say 천천히 걸어요 or 걸음이 느려요.

빨리 vs 천천히 vs 일찍 in real speech

빨리 is everywhere in Korea — it's the word behind the famous 빨리빨리 habit of getting things done now. It can be a request, a nudge, or a mild scolding depending on your tone.

• 빨리 와! — Hurry up and come! (반말, to a close friend)
• 빨리 해 주세요. — Please do it quickly.
• 배가 고파요. 빨리 먹읍시다. — I'm hungry. Let's eat quickly.

Its opposite in conversation isn't 늦게 but 천천히 — "slowly, take your time." 천천히 is one of the kindest words in Korean:

• 천천히 하세요. 안 급해요. — Take your time. There's no rush.
• 천천히 드세요. — Enjoy your meal slowly. (Said when someone is wolfing down food.)
• 천천히 말해 주시겠어요? — Could you speak slowly?

If you want to soften any of these, 조금만 or 좀 slots right in front: 조금만 천천히요.

One more place you'll meet 빠르다 constantly: shipping. 빠른 배송 means fast delivery, and 빨리 오면 좋겠어요 ("I hope it comes soon") is what every online shopper mutters. If that's your world, the difference between 배달, 택배 and 배송 is worth five minutes.

The one idea to keep

Before you choose, ask yourself: am I talking about speed, or about the clock? Speed → 빠르다 / 느리다 / 빨리 / 천천히. Clock → 이르다 / 늦다 / 일찍 / 늦게. English blurs the two; Korean doesn't, and native speakers hear the difference instantly.

FAQ

What is the difference between 빨리 and 일찍 in Korean?

빨리 means "quickly" and describes speed — how little time something takes. 일찍 means "early" and describes a point on the clock. 빨리 오세요 tells someone to hurry; 일찍 오세요 tells them to arrive at an early hour. If you woke up at 5 a.m., that's 일찍 일어났어요, not 빨리 일어났어요.

Does 늦다 mean "late" or "slow" in Korean?

늦다 means late — behind the time something was supposed to happen. For "slow," use 느리다 (speed) or the adverb 천천히. So 늦어서 죄송합니다 is "sorry I'm late," while 인터넷이 느려요 is "the internet is slow." Swapping them is one of the most common learner errors.

How do you say "take your time" in Korean?

Say 천천히 하세요 — literally "do it slowly," and warmly meant. You can add 안 급해요 ("there's no rush") after it. To ask someone to speak more slowly, say 조금만 천천히 말해 주세요.
