Korean Subject in Korean: What Does 국어 Mean?
국어 means the Korean language as a school subject and the national language. It is used from a Korean point of view: for Korean as a foreign language, people say 한국어 instead. So the word marks a viewpoint as much as a subject.
How Do You Pronounce 국어?
Romanized gugeo. Two syllables, gu-geo: the final ㄱ of 국 moves into the second syllable because 어 starts with a silent ㅇ, and between vowels it sounds like a soft g.
Example Sentences with 국어
국어 시간에 시를 읽어요.
Gugeo sigane sireul ilgeoyo.
We read poems in Korean class.
시간 is hour or period, so 국어 시간 is the Korean class slot. 시 is poem, and 읽어요 is read.
국어 숙제를 했어요.
Gugeo sukjereul haesseoyo.
I did my Korean homework.
숙제 is homework and 했어요 is the past of doing. The line is a school-day report.
오늘 국어 시험이 있어요.
Oneul gugeo siheomi isseoyo.
I have a Korean exam today.
시험 is exam. 있어요 means there is, so the sentence says there is an exam today (오늘).

Foreign learners often borrow the school word for their own lessons.
- Wrong: 국어 수업 for a foreigner's Korean class.
- Correct: 한국어 수업. 국어 is the subject Korean students take in their own schools.
국어 Compared with Similar Words
한국어 is Korean as a language for foreigners and general use. 영어 is English, the other school subject that sits beside it in most timetables.
| Word | Meaning | How it differs |
|---|---|---|
| 한국어 | Korean (language) | 한국어 is Korean as a language for foreigners and general use. |
| 영어 | English | 영어 is English. |
Where Does the Word Come From?
국어 is Sino-Korean, written 國語 in hanja. The first character means country and the second means language, so the word reads as "the language of the country".
Cultural Note
In Korean schools, 국어 is a core subject alongside math and English.
Packing for a School Day
Two classmates check what to bring for their next lesson. They are discussing the Korean subject on their school timetable.
Jisu
다음 시간은 국어예요?
Daeum siganeun gugeoyeyo?
Is the next class Korean?
Minho
네. 국어 교과서 가져왔어요?
Ne. Gugeo gyogwaseo gajyeowasseoyo?
Yes. Did you bring your Korean textbook?
Jisu
네. 국어 숙제도 했어요.
Ne. Gugeo sukjedo haesseoyo.
Yes. I did my Korean homework too.
Minho
좋아요. 같이 교실에 가요.
Joayo. Gachi gyosire gayo.
Good. Let’s go to the classroom together.
국어예요 joins 국어 to the polite “is” ending 예요 because the noun ends in a vowel. 국어 숙제도 adds 도, “too”, to the homework phrase. The classmates use polite endings here; close school friends may use casual speech. The subject name itself stays the same.
Where Will You See 국어?
A school timetable may list 국어 beside 수학, math, and 영어, English. On a timetable, the short label names the subject; the number or position of the cell supplies the class period. In a school conversation, 국어 시간 refers to that period, rather than a general amount of time spent learning Korean.
On a textbook cover or in a bookshop’s school section, 국어 points to materials for studying the subject. These can involve reading passages, literature and writing. A beginner’s 한국어 textbook usually has a different purpose: helping someone learn Korean as an additional language. Looking at the title alone is less useful than checking who the book is for.
국어 is also used beyond classrooms. 국어사전 means a Korean-language dictionary, often one explaining Korean words in Korean. Seeing 국어 in that compound does not mean the dictionary is restricted to schoolchildren. The broader “national language” sense explains why the word appears in reference-book titles.
What Do the School Phrases Actually Mean?
국어 시험 is an exam in the school subject. The phrase does not automatically mean a proficiency test for learners of Korean. In a conversation about a child’s school day, it may concern the texts and skills taught in class. The setting identifies the kind of exam.
국어 선생님 means the teacher responsible for that subject. As with other subject names, put 국어 before 선생님 without an object marker. 국어 시간 similarly joins two nouns. In 국어 시간에, the particle 에 attaches at the end of the whole phrase to mean “during Korean class”.
The example 국어 시간에 시를 읽어요 gives a useful clue about the lesson: students read poems. Recognizing the individual words in a poem is only part of that task; discussing what the poem means belongs to the school subject too. This helps explain why 국어 and a beginner’s 한국어 class can feel very different.
Words beside 국어 on a School Day
| Korean | Meaning | Useful note |
|---|---|---|
| 수학 | mathematics | A separate subject on the timetable. |
| 교과서 | school textbook | The book used for a school subject. |
| 숙제 | homework | Put the subject before it to identify the assignment. |
| 시간표 | timetable | Shows when each subject is taught. |
The school subjects lesson teaches the wider set of subject names. Learning those names together helps you read a timetable without translating every box as a separate sentence.
