🧩 Sino-Korean and Native Vocabulary β€” ν•œμžμ–΄μ™€ κ³ μœ μ–΄

Korean vocabulary has two big layers. κ³ μœ μ–΄ (native words) are the everyday, home-grown words. ν•œμžμ–΄ (Sino-Korean words) were built from Chinese-character roots and make up a large share of the dictionary, especially in formal, academic and technical language. Once you know a few dozen roots, you can read and even guess hundreds of words. Each root below is shown with the word it appears in; the characters are not needed, only the sound and meaning.

The rule in one box Native words feel everyday and concrete; Sino-Korean words feel formal and abstract. Sino-Korean roots are one syllable each and combine like building blocks (ν•™ + ꡐ β†’ 학ꡐ). Add -적, -ν™”, -μ„± to make new abstract words, 뢈-, 무- to make negatives, and ν•˜λ‹€ / λ˜λ‹€ / μ‹œν‚€λ‹€ to turn a noun into a verb.

Native and Sino-Korean pairs

Many ideas have both a native and a Sino-Korean word. The Sino-Korean one is usually the more formal or written choice.

Native (everyday)Sino-Korean (formal)Meaning
이름성λͺ…name
λ‚˜μ΄μ—°λ Ήage
λͺΈμ‹ μ²΄body
κΈΈλ„λ‘œroad, way
λ°₯식사meal
ν•΄νƒœμ–‘the sun

Two number systems

The same split runs through numbers. Sino-Korean numbers (일, 이, 삼…) are used for dates, minutes, money, floors and phone numbers. Native numbers (ν•˜λ‚˜, λ‘˜, 셋…) are used for counting items, people and hours.

UseExample
Date, money (Sino)μ‚Όμ›” 였일, 이천 원
Counting people, things (native)μ„Έ λͺ…, 두 개
Clock time (both)μ„Έ μ‹œ 이십 λΆ„ (hour native, minute Sino)

Common roots

Learn the root from words you already know, then spot it in new ones.

Suffixes: -적, -ν™”, -μ„±

SuffixEffectExamples
-적"-ic", "-al"; makes a noun describe something경제적, 개인적, 일반적
-ν™”"-ization", becoming세계화, ν˜„λŒ€ν™”, λ„μ‹œν™”
-μ„±"-ness", "-ity"; a qualityκ°€λŠ₯μ„±, μ€‘μš”μ„±, ν•„μš”μ„±
-자a person who doesν•™μž, 기자, μ†ŒλΉ„μž

A -적 word attaches to a following noun with -인 (경제적인 문제, "an economic problem") or to a verb with -으둜 (경제적으둜 μ–΄λ ΅λ‹€, "economically difficult").

Prefixes: 뢈-, 무-, λΉ„-, λ―Έ-

PrefixMeaningExamples
뢈-not, un-λΆˆκ°€λŠ₯, 뢈편, λΆˆν–‰, 뢈만
무-without, lacking무관심, λ¬΄μ±…μž„, 무료
λΉ„-non-비곡식, 비정상
λ―Έ-not yetλ―Έμ™„μ„±, 미확인

Before the sounds γ„· and γ…ˆ, 뢈- becomes λΆ€-: λΆ€μ‘± ("shortage"), λΆ€μ • ("denial").

Noun + ν•˜λ‹€ / λ˜λ‹€ / μ‹œν‚€λ‹€

A Sino-Korean noun becomes a verb by adding one of three endings. Choose by the direction of the action.

EndingMeaningExample
-ν•˜λ‹€do it (active)νšŒμ‚¬κ°€ κ³„νšμ„ κ²°μ •ν–ˆλ‹€. The company decided the plan.
-λ˜λ‹€it happens / is done (passive, intransitive)κ³„νšμ΄ κ²°μ •λ˜μ—ˆλ‹€. The plan was decided.
-μ‹œν‚€λ‹€make someone or something do it (causative)μ„ μƒλ‹˜μ΄ 학생을 μ΄ν•΄μ‹œμΌ°λ‹€. The teacher made the student understand.

The same noun can take all three: μ‹œμž‘ν•˜λ‹€ ("start", with an object), μ‹œμž‘λ˜λ‹€ ("begin", on its own).

Watch out: formal does not always mean better Sino-Korean words sound formal and precise, but a chain of them in speech can sound stiff. Say λ°₯ λ¨Ήμ—ˆμ–΄μš”? to a friend, not μ‹μ‚¬ν•˜μ…¨μŠ΅λ‹ˆκΉŒ? unless the situation is formal. Also, a sound can stand for several roots, as with 사고 ("accident") and 사고 ("thinking"). Context decides.
