Korean Numbers: Counters with Native Korean Numbers

Most counters pair with Native Korean numbers: 한 개, 두 명, 세 마리. The number comes AFTER the noun and BEFORE the counter: 사과 한 개 (apple one piece).

The Rule

Most counters pair with Native Korean numbers: 한 개, 두 명, 세 마리. The number comes AFTER the noun and BEFORE the counter: 사과 한 개 (apple one piece). Korean has TWO completely separate number systems — Native Korean (하나, 둘, 셋) and Sino-Korean (일, 이, 삼). English speakers must learn WHEN to use which system, because mixing them up is a common and noticeable mistake.

Why English Speakers Get It Wrong

English has one number system. Korean has two, and you must pick the RIGHT one depending on what you're counting. Using Sino-Korean where Native Korean is required (or vice versa) sounds as wrong to Koreans as saying "I have three-th cats" sounds in English. Key numbers for this topic: • 개 (gae) = general items • 명 (myeong) = people • 마리 (mari) = animals • 잔 (jan) = cups/glasses • 병 (byeong) = bottles • 권 (gwon) = books

How It Works

Most counters pair with Native Korean numbers: 한 개, 두 명, 세 마리. The number comes AFTER the noun and BEFORE the counter: 사과 한 개 (apple one piece). Examples: • 커피 두 잔 주세요. (keopi du jan juseyo.) — "Two cups of coffee, please." • 고양이 세 마리 있어요. (goyangi se mari iteoyo.) — "I have three cats." • 책 다섯 권 읽었어요. (chaek daseot gwon ireoteoyo.) — "I read five books." The word order is: Noun + Native Number + Counter. 사과(apple) 세(three) 개(pieces). Remember: 하나→한, 둘→두, 셋→세, 넷→네 when followed by counters. This shortening is mandatory, not optional.

Real Examples

• 커피 두 잔 주세요. (keopi du jan juseyo.) — "Two cups of coffee, please." • 고양이 세 마리 있어요. (goyangi se mari iteoyo.) — "I have three cats." • 책 다섯 권 읽었어요. (chaek daseot gwon ireoteoyo.) — "I read five books."

Common Mistakes

❌ Using the wrong number system for the context ✅ Counters with Native Korean Numbers uses Native Korean numbers → Each context has a fixed number system. Memorize which system goes with which context. ❌ Forgetting the shortened forms (하나→한, 둘→두, etc.) ✅ Native Korean numbers 1-4 change form before counters → This is mandatory, not optional. 하나 개 is wrong; 한 개 is correct.

Quick Tip

The word order is: Noun + Native Number + Counter. 사과(apple) 세(three) 개(pieces). Remember: 하나→한, 둘→두, 셋→세, 넷→네 when followed by counters. This shortening is mandatory, not optional. Practice tip: Pick one number context (like ordering food or telling time) and drill it until it's automatic. Don't try to learn both systems at once — master one usage scenario at a time.
