解説 이수하다 in your Level:

At the A1 level, '이수하다' is quite difficult. You don't need to use it yourself yet. Instead, you usually use the word '듣다' (to listen/take) or '하다' (to do). For example, instead of '이수하다', an A1 learner would say '수업을 들었어요' (I took the class) or '공부를 끝냈어요' (I finished studying). Think of '이수하다' as a 'super-formal' way to say 'I finished a class.' You might see it on a school website, but you can just remember it means 'finished a course.' Focus on the '이' and '수' sounds and associate them with school credits. At this stage, just knowing it's related to finishing school requirements is enough. Don't worry about the complex Hanja (Chinese characters) behind it yet.

At the A2 level, you are starting to encounter more formal situations, such as at a university office or a job center. You might see '이수' on a sign or a form. You should recognize that this word is specifically for finishing a class or training. While you still might use '수업을 다 들었어요' (I took all the classes) in daily life, you should understand when a teacher says '이 과목을 이수해야 해요' (You must complete this subject). It's a 'Level Up' word from '끝내다'. Start noticing that it's always used with things like '학점' (credits) or '과목' (subjects). It's like a special key that unlocks graduation.

This is the level where you should actively start using '이수하다'. As a B1 learner, you are expected to handle administrative tasks in Korean. If you are a student in Korea, you need this word to talk about your major (전공) and graduation (졸업). You should know the difference between '수강하다' (to take/register) and '이수하다' (to complete). Use '이수하다' when you want to sound professional or when you are discussing official requirements. For example, '저는 한국어 교육 과정을 이수했습니다' sounds much more impressive and accurate than '한국어 공부를 다 했어요' when you are applying for a job or a higher-level course.

At B2, you should be comfortable with the nuances of '이수하다' and its related terms. You should understand that '이수' implies not just attending, but meeting all criteria (attendance, exams, assignments). You should be able to use it in the passive or noun form, such as '이수 학점' (completed credits) or '이수 요건' (completion requirements). You will encounter this word in news articles about education policy or legal requirements for professional licenses. You should also be able to distinguish it from '수료하다' (completing a non-degree program). It's an essential word for the TOPIK II exam, especially in the writing section where formal vocabulary is required.

At the C1 level, you use '이수하다' effortlessly in academic and professional discourse. You understand the Hanja roots (履 - to tread, 修 - to study) and how they relate to other words like '수행하다' (to perform) or '수정하다' (to modify). You can discuss complex educational systems and the '이수 체계' (curriculum system) of different institutions. You might use it in legal contexts, such as '의무 교육 이수' (completion of compulsory education). You are also aware of the social implications of '이수' in Korea's competitive society, where '미이수' (non-completion) can have serious career consequences. You can use it to describe fulfilling statutory requirements in any professional field.

At the C2 level, '이수하다' is just one of many precise tools in your vocabulary. You can use it to critique educational policies or discuss the '학점 이수제' (credit completion system) in depth. You understand the subtle differences in tone between '이수', '수료', '졸업', and '학위 취득'. You can write formal academic papers or legal documents where this word is used to define the boundaries of professional qualification. You might use it metaphorically or in very specific technical contexts, such as '연수 과정 이수' in high-level corporate training. Your usage is indistinguishable from a native speaker who has navigated the Korean higher education system.

練習する例文メモとヒント

이수하다 30秒で

Formal verb for completing a course or credits.
Essential for university and professional contexts.
Indicates fulfillment of official requirements.
Derived from Hanja meaning 'to tread the path of study'.

The Korean verb 이수하다 (isu-hada) is a formal academic and administrative term that translates to 'to complete a course of study' or 'to fulfill the requirements of a specific curriculum.' While the English word 'take' is often used loosely for attending a class, 이수하다 carries a much heavier weight of completion and official recognition. It is derived from the Hanja 履 (신 리/이 - to tread/fulfill) and 修 (닦을 수 - to study/cultivate), literally meaning to 'tread the path of cultivation' or to finish the required steps of learning. In the context of South Korean society, where education and certification are highly valued, this word appears constantly in university handbooks, job descriptions, and professional licensing requirements.

Academic Context: This is the primary domain for the word. Students do not just 'take' (듣다) a class; they must 'complete' (이수하다) it to receive credit. If a student fails or drops out, they have not 'completed' the course. For example, '전공 필수 과목을 이수해야 졸업이 가능합니다' (You must complete the mandatory major subjects to be able to graduate).

졸업을 하려면 반드시 140학점을 이수해야 합니다. (To graduate, you must complete 140 credits.)

Professional/Legal Context: Outside of school, this word is used for mandatory training sessions. For instance, a driver who committed a violation might have to '이수하다' a safety education program. In a job setting, employees might need to '이수하다' a sexual harassment prevention course annually. It implies that there is a set curriculum with a beginning and an end that must be satisfied.

Furthermore, the word is frequently paired with specific nouns like 학점 (credits), 과목 (subjects), 과정 (course/process), and 교육 (education). In the Korean job market, applicants often list '이수 과목' (completed subjects) on their resumes to prove they have the necessary background for a role. This is particularly common for specialized roles like engineering or accounting where specific certifications are required.

그는 해외 연수 과정을 성공적으로 이수했다. (He successfully completed the overseas training course.)

Distinction from '졸업하다': While '졸업하다' (to graduate) refers to the final act of leaving an institution with a degree, '이수하다' refers to the individual steps or the total sum of credits needed to get there. You can '이수' all your credits but still not '졸업' if you haven't passed a thesis or a graduation exam.

Using 이수하다 correctly requires understanding its grammatical placement and the formal nuance it brings to a sentence. It is an active verb that takes an object, usually marked by the particle 을 or 를. Because it is a formal word, it is most commonly found in written documents, official announcements, or polite spoken Korean (using -습니다 or -어요 endings).

신입 사원들은 2주간의 입사 교육을 이수해야 합니다. (New employees must complete a two-week introductory training.)

One of the most common sentence patterns involves the 'must' structure: -아/어/여야 하다. This is because '이수하다' is inherently linked to requirements. For example, '교직 이수를 위해 이 과목을 들어야 해요' (I have to take this subject for the completion of the teaching curriculum). Here, '이수' is used as a noun, which is also very common. The noun form 이수 can be combined with other nouns to create compound terms like 이수 학점 (completed credits) or 이수증 (certificate of completion).

Passive vs. Active: While you '이수' a course, a course can be '이수되다' (to be completed). However, '이수되다' is much less common than the active form. Usually, we focus on the person fulfilling the requirement.

그는 이미 필요한 모든 학점을 이수한 상태입니다. (He is in a state where he has already completed all necessary credits.)

In academic counseling, you might hear questions like '전공 과목을 몇 학점이나 이수하셨나요?' (How many credits of major subjects have you completed?). Notice the use of the honorific '시' in '이수하셨나요' to show respect to the student or professional being asked. In contrast, when talking about yourself in a job interview, you would say '저는 경영학 원론을 이수했습니다' (I completed the Principles of Management).

컴퓨터 활용 능력 교육을 이수하면 가산점을 받을 수 있습니다. (If you complete the computer literacy training, you can receive extra points.)

You are unlikely to hear 이수하다 while hanging out with friends at a cafe unless you are specifically discussing graduation requirements or bureaucratic hurdles. Instead, this word lives in formal environments. If you walk into a University Administration building (교무처), you will see signs about '이수 학점 안내' (Information on completed credits). When you log into a Korean university's student portal, the '이수 현황' (Completion status) section will show you which classes you've successfully finished.

학생지원처: "졸업을 위해 사회봉사 30시간을 이수하셔야 합니다." (Student Services: "You must complete 30 hours of community service for graduation.")

Another common place is in the corporate world. Every year, Korean companies require employees to undergo various '법정 의무 교육' (legally mandatory education). After watching a series of videos or attending a seminar, the system will record that you have '이수'ed the course. You might receive an '이수 확인서' (Confirmation of completion) to submit to HR. In news reports, you might hear about government officials or public figures who are required to '이수' certain ethics or leadership programs.

Military Context: In the South Korean military, soldiers and reservists must complete specific training cycles. You will hear terms like '예비군 훈련 이수' (Completion of reservist training). Failing to '이수' these can lead to legal penalties.

뉴스: "해당 자격증을 취득하려면 먼저 이론 교육을 이수해야 합니다." (News: "To obtain the license in question, one must first complete theoretical training.")

Finally, in the age of online learning, platforms like Coursera or Korean equivalents like K-MOOC use '이수' to describe finishing a digital course. When you finish all the modules, the button usually changes to '이수 완료' (Completion Finished).

The most frequent mistake learners make with 이수하다 is using it in casual conversation where '듣다' (to listen/take) or '공부하다' (to study) would be more natural. If you tell a friend, '나 오늘 수학 수업 이수했어' (I completed math class today), it sounds like you just finished the entire semester's requirements or graduated from the course, rather than just attending a single lecture. For a single day's class, use '수업 들었어'.

Confusing with '수료하다': While very similar, '수료하다' (to finish a course) is often used for non-degree programs or short-term workshops. '이수하다' is more common for formal 'credits' (학점) in a university setting. You '이수' credits to '수료' or '졸업' a program.

Wrong: 어제 역사 수업을 이수했어요. (I completed history class yesterday - implies the whole course was finished in one day.)
Right: 어제 역사 수업을 들었어요. (I took/attended history class yesterday.)

Another mistake is forgetting the object marker. Since '이수하다' is a transitive verb, you must specify *what* was completed. You cannot simply say '저는 이수했습니다' without context. You must say '저는 [과정]을 이수했습니다'.

Misusing with '공부하다': '공부하다' is the act of studying. '이수하다' is the administrative result of that study. You study (공부하다) to complete (이수하다) the course. You wouldn't say '시험을 위해 이수하고 있어요' (I am completing for the exam); you would say '시험을 위해 공부하고 있어요'.

To truly master 이수하다, you need to know its neighbors in the semantic field of 'education and completion.' Depending on the level of formality and the specific context, other words might be more appropriate.

이수하다 vs. 수강하다: 수강하다 (Take/Attend a lecture): This focuses on the act of attending or registering for a class. You '수강' a class at the beginning of the semester. You '이수' it at the end once you've passed.
이수하다 vs. 수료하다: 수료하다 (Finish a program): Usually refers to finishing a whole program (like a 6-month language course) rather than individual credits. '이수' is the brick, '수료' is the wall.
이수하다 vs. 듣다: 듣다 (Listen/Take): The most common, casual way to say you are taking a class. '이번 학기에 뭐 들어?' (What are you taking this semester?). You would never say '뭐 이수해?' in this casual context.

Comparison:
1. 수강 (Registration/Attendance)
2. 이수 (Completion of credits)
3. 수료 (Completion of a program)
4. 졸업 (Graduation/Degree attainment)

In professional settings, you might also encounter 마치다 (to finish) or 끝내다 (to end). These are generic and can be used for anything from a meal to a movie. 이수하다 is strictly reserved for organized learning and requirements. If you are describing a training you did at work, '교육을 마쳤습니다' is natural, but '교육을 이수했습니다' sounds more professional and suggests there was an official record of it.

How Formal Is It?

Derived from the Hanja characters 履 (신 리/이) and 修 (닦을 수). 履 means 'to tread' or 'to carry out,' while 修 means 'to study,' 'to cultivate,' or 'to repair.'

元の意味： To tread the path of self-cultivation or study.

Sino-Korean (Hanja-based).

文化的な背景

Be careful not to confuse '이수' with '수료' in formal documents, as they can have different legal implications for visa or job applications.

In English, we usually say 'I took a class' or 'I finished a course.' 'Complete' is the closest formal equivalent, but '이수하다' is used much more frequently in daily administrative life in Korea than 'complete' is in the US/UK.
