Korean Word Types: Sino-Korean, Loanwords, Onomatopoeia, Idioms

Korean Word Types at a Glance

Korean word types are the three layers that make up the vocabulary: native Korean words, Sino-Korean words and loanwords. Native words are the oldest and most everyday. Sino-Korean words are built from Chinese-origin syllables and sound formal. Loanwords come from other languages, mostly English. Each layer behaves differently in grammar, in politeness and in spelling, and the six lists on this site follow those layers and the special word kinds that grow from them.

The three layers sit side by side for the idea of a meal. A friend asks 밥 먹었어요? (Did you eat?) in everyday speech. A formal host says 식사하세요 (Please have your meal). A shop sells a 밀키트. All three are correct Korean, and the layer tells you the setting. Press the buttons to hear them.

The exact share of each layer in the dictionary is counted by the National Institute of Korean Language (국립국어원) in its Standard Korean Dictionary (표준국어대사전). This page gives no percentages, because the counts depend on what the count includes. The main point for a learner is simple: Sino-Korean words are very numerous, and they follow repeating patterns.

Why Does Word Type Matter?

Word type predicts how a word behaves, so it saves you time. Four effects are worth knowing from the start.

1. Verbs. Many Sino-Korean and loanword nouns add 하다 to make a verb: 공부하다 (study) and 쇼핑하다 (shop). Most native verbs are simple stems: 먹다 (eat). A few native nouns take 하다 too, as in 일하다 (work), so treat this as a strong tendency, not a rule.
2. Numbers. Korean has two number systems, one native (하나, 둘, 셋) and one Sino-Korean (일, 이, 삼). The split is the same split as the word layers. The Korean numbers pages explain which system goes with which counter.
3. Politeness. A Sino-Korean word is often the formal choice and the native word the everyday one: 식사 and 밥, as in the table. Switching layers is one way to change register.
4. Guessing new words. Sino-Korean syllables repeat. The syllable 학 appears in 학교 (school), 학생 (student) and 대학 (university). Once you know it, new words become easier to read. The Hanja section shows the characters behind those syllables.

These effects mean that a learner who knows the layer of a word can guess its grammar, its register and often its meaning.

Which List Should You Open First?

Open the list that matches your goal. The table gives a first pick, the Korean example you will meet there, and an editorial level estimate. The levels are estimates, not official levels.

If you are not sure, start with Sino-Korean words. They are the largest layer, and their syllables recur in most of what you will read.

Sino-Korean Words

The Sino-Korean Words list holds 50 words in 5 groups, plus the key syllables and the word-building patterns behind them. You will meet 학교 (school) and 학생 (student), and see how one syllable carries one core meaning across many words. Open it when you want to read signs, news and school texts, or when you want to see why a new word feels familiar. It is the best list to read before any of the others.

What Is in the Loanwords and Konglish List?

The Konglish and Loanwords list holds 50 words in 5 groups of 10. It separates plain English loanwords such as 컴퓨터 from Konglish words that Koreans built from English parts, such as 핸드폰 (mobile phone). It also covers Japanese-origin words and their standard replacements, the sound rules that reshape English, and false friends such as 서비스 (a free extra). Two deeper pages follow it: Konglish examples and false friends and how English words sound in Korean.

Onomatopoeia and Mimetic Words

The Onomatopoeia and Mimetic Words list holds 50 words in 5 groups of 10. Onomatopoeic words imitate sounds, such as 멍멍 (woof), and mimetic words describe appearances and movements, such as the way something shines or wobbles. Korean uses this layer much more than English does, in speech, comics and dramas. Light vowels such as ㅏ and ㅗ feel small and sharp, and dark vowels such as ㅓ and ㅜ feel big and heavy.

Idioms, Proverbs and Four-Character Idioms

Three lists follow the form of an expression rather than its origin. Korean Idioms teaches 40 fixed phrases with their literal images, starting with 손이 크다, literally 'the hand is big', which means generous. Korean Proverbs teaches 40 속담 (sokdam), traditional sayings such as 시작이 반이다, with English equivalents where one exists. Four-Character Idioms teaches 40 사자성어 with their Hanja, such as 일석이조 (一石二鳥). Read the Sino-Korean list first if you can, because most four-character idioms are built from Sino-Korean syllables.

What Do All the Lists Have in Common?

Every list follows the same format, so you can move between them without relearning how to read the page.

• Hangul first. Each word or expression is written in Hangul, and the Revised Romanization is a learning aid in parentheses, never the only form.
• Audio. Each entry has an audio clip. The audio is generated with text-to-speech and checked by a Korean teacher before publication.
• An example sentence. Each entry has one short example, so you see how the word is used.
• Plain level labels. Levels are editorial estimates, not official levels.
• Practice. Each list links to flashcards and a worksheet.

For verbs and adjectives, which belong to every layer, see the verbs hub. Slang is a separate topic, covered in Korean Slang.

Frequently Asked Questions

Which List in Korean Word Types Should I Start With?

Start with Sino-Korean Words if you want to read news and school texts, or with Konglish and Loanwords if you want to recognise English-looking words quickly. If you have no preference, begin with the Sino-Korean list, because it is the largest layer and its syllables repeat across many other words.

How Are the Lists in Korean Word Types Organised?

The six lists follow two ideas. Three of them follow the origin of the words: Sino-Korean words, loanwords and Konglish, and the native sound words in onomatopoeia. The other three follow the form of the expression: idioms, proverbs and four-character idioms. Each list has Hangul, Revised Romanization, audio and an example sentence.

Do These Lists Include Verbs and Adjectives?

Not as a separate group. Verbs and adjectives belong to the verbs section, which has conjugation tables and a verb dictionary. The word type lists include some predicates inside idioms and examples, such as 공부하다 (study) and 먹다 (eat), but they teach the vocabulary layers, not the conjugation.

Where Can I Find Flashcards and Worksheets for These Topics?

The vocabulary flashcard decks page lists every deck with audio, and the vocabulary worksheets page lists the printable sheets. Decks for some of these lists are planned and are not published yet. Progress in the decks stays in your browser.

Is the Romanization on These Pages Official?

It follows the Revised Romanization of Korean, which South Korea officially adopted on 7 July 2000 and whose rules the National Institute of Korean Language (국립국어원) publishes. It is a learning aid that does not show tensing caused by a neighbouring sound, so learn the Hangul and use the audio to hear the real sound.
