A Korean dictionary for learners is a reference that gives Hangul headwords, English meanings, example sentences and ideally audio, available online, as apps and in print. This page explains the four types of Korean dictionary, the free official ones, how to look up a word you met in a conjugated form, and why a translator is a different tool. It ends with the six criteria we use to compare any dictionary.

Which Korean Dictionary Should You Use?

Study Which Korean dictionary should you use.

Use the type of dictionary that matches your level and the question you are asking. Most learners need two: a bilingual dictionary for quick meanings and a learner or monolingual dictionary for precise ones.

Type What it gives you Best for Example
Bilingual (Korean–English) English meanings, often with audio and examples All levels; quick lookups Portal dictionaries such as Naver Dictionary
Learner dictionary Simple definitions, graded examples, translations into several languages A1–B1 Korean Learners' Dictionary (한국어기초사전), free from the National Institute of Korean Language
Monolingual (Korean–Korean) Definitions in Korean, standard spelling and spacing, hanja origin B1 and up; checking exact usage Standard Korean Language Dictionary (표준국어대사전); 우리말샘 for newer words
Hanja dictionary The Chinese characters behind Sino-Korean words and their meanings B1 and up; building word families Hanja sections of portal dictionaries

The Standard Korean Language Dictionary is the reference for standard spelling and spacing. 우리말샘 (urimalsaem) is a larger, open dictionary from the same institute that also records newer words and regional forms, so it is the place to look when a word is missing from the standard dictionary. All three official dictionaries are free online.

How Do You Look up a Korean Word You Heard?

Study How do you look up a Korean word you heard.

Look up the dictionary form, also called the base form. Korean dictionaries list every verb and adjective under a form ending in -다, not under the forms you meet in sentences. Strip the ending and add -다:

You meet Dictionary form Meaning What changed
먹었어요 (meogeosseoyo) [머거써요] 먹다 (meokda) [먹따] to eat the past polite ending -었어요 is removed
예뻐요 (yeppeoyo) 예쁘다 (yeppeuda) to be pretty the ㅡ of 쁘 drops before -어요, so add it back
들어요 (deureoyo) [드러요] 듣다 (deutda) [듣따] or 들다 (deulda) to listen, or to lift two different verbs share this form

The third row shows why this skill matters. 들어요 comes from 듣다 (an irregular verb whose ㄷ becomes ㄹ before a vowel) and also from 들다. Only the sentence tells you which: 음악을 들어요 (eumageul deureoyo, I listen to music) uses 듣다.

Many dictionary apps now guess the base form for you, but they can guess wrong in exactly these cases. The Korean verb list on this site shows the main conjugated forms of common verbs side by side, which makes this kind of lookup faster.

Why Is a Translator Not a Dictionary?

Study Why is a translator not a dictionary.

A dictionary shows you every meaning of one word, with examples, and lets you choose. A translator turns a whole sentence into another language and chooses for you, usually without showing the alternatives. That difference causes three common problems for learners:

  • Politeness. Korean has several speech levels. A translator may give you a casual or overly formal ending that does not fit the person you are writing to.
  • The word "you". Translators often turn "you" into 당신 (dangsin). In most conversations Koreans use the person's name or title, or leave "you" out, so 당신 can sound distant or even confrontational.
  • Hidden ambiguity. As with 들어요 above, one Korean form can come from two words. A translator picks one without telling you.

Use a translator for the gist of a long text, then check each important word in a dictionary. Before you send a message, run it through a spell checker, which flags spelling and spacing errors that a translator will not.

How Does Hanja Help with Korean Vocabulary?

Study How does hanja help with Korean vocabulary.

Hanja are the Chinese characters behind Sino-Korean words, which make up a large share of Korean vocabulary. A hanja dictionary shows the character behind each syllable, so you can see word families. For example, 학생 (haksaeng) [학쌩], student, and 학교 (hakgyo) [학꾜], school, share 학 (學), "learn". You do not need to write hanja, but knowing one character often unlocks several words.

How Do We Compare Dictionaries?

Study How do we compare dictionaries.

Every dictionary and tool in this section is judged on six criteria:

  1. Headword coverage. Does it include everyday words, newer loanwords and set phrases?
  2. English glosses. Are the English meanings precise, and are different senses separated?
  3. Example quality. Are the example sentences natural and labelled by source? Examples collected from the web vary in quality.
  4. Audio. Is there audio for headwords and examples, and is it recorded or generated?
  5. Search tolerance. Does it find a word from a conjugated form, a typo or romanized input?
  6. Offline use. Does it work without a connection?

We give no ratings, take no payment from any tool, and note the date each page's facts were checked.

Frequently Asked Questions

Which Korean dictionary should I use? As a beginner, use a bilingual Korean–English dictionary with audio and example sentences, plus the free Korean Learners' Dictionary (한국어기초사전) from the National Institute of Korean Language. From about B1, add the Standard Korean Language Dictionary (표준국어대사전) for exact spelling, spacing and definitions in Korean.

Is Google Translate a dictionary? No. A translator turns whole sentences into another language and picks one meaning for you, often without showing the others. It can choose the wrong politeness level or add 당신 for 'you', which sounds odd in most conversations. Use it for the gist of a long text, then check single words in a dictionary.

Do I need a Korean-Korean dictionary? Not at first. A monolingual dictionary defines Korean words in Korean, so it becomes useful around the intermediate level, when you can read simple definitions. It gives more precise meanings, the standard spelling and spacing, and the hanja behind Sino-Korean words, which English glosses often leave out.

Is there an offline Korean dictionary? Yes. A print dictionary always works offline, and some dictionary apps let you download word data for offline use, usually with fewer examples and no audio. The official online dictionaries need a connection. If you study on flights or commutes, check an app's offline option before you rely on it.

How much does a Korean dictionary cost? The official dictionaries of the National Institute of Korean Language are free online, and the main portal dictionaries are free to use with ads. Paid options are print dictionaries and some apps with offline data or extra features. Check current prices in the shop or app store, because they change.
