解説 집중력 in your Level:

At the A1 level, you don't need to use '집중력' (concentration ability) often. Instead, you'll likely use the simpler word '집중' (focus). However, it's good to recognize '집중력' in very simple sentences about studying. You might say '집중력이 좋아요' (Focus is good) or '집중력이 없어요' (I have no focus). At this stage, focus on the fact that '력' means 'power' or 'strength.' Think of it as 'brain power' for studying. You will mostly hear this from teachers or parents. Just remember that it's a noun. You cannot say '집중력해요.' You must say '집중력이 있어요.' Keep your sentences short and focus on the basic 'Subject + Particle + Adjective' structure. For example, '제 집중력은 짧아요' (My concentration span is short). This level is about building the foundation of the word's meaning as a mental resource.

For example, '피곤해서 집중력이 떨어졌어요' (I'm tired, so my concentration dropped). You should also be able to understand simple advice, such as '집중력을 높이세요' (Increase your concentration). You will notice that '집중력' is often followed by the particle '-이/가' when it's the thing that is changing (dropping, being good). You can also use it to describe other people simply, like '우리 형은 집중력이 정말 좋아요' (My brother's concentration is really good).

집중력 30秒で

집중력 means 'concentration power' or 'the ability to focus'.
It is a noun used to describe mental stamina and focus quality.
Commonly used in Korean schools and offices to discuss productivity.
Pair it with verbs like '높이다' (increase) or '떨어지다' (decrease).

The Korean word 집중력 (Jip-jung-ryeok) is a cornerstone of Korean society, particularly in the realms of education, professional performance, and personal development. At its core, it refers to the mental stamina and the specific ability to sustain focus on a single task without being distracted by external or internal stimuli. The word is composed of three Hanja characters: 集 (Jip) meaning 'to gather,' 中 (Jung) meaning 'center' or 'middle,' and 力 (Ryeok) meaning 'power' or 'force.' Therefore, etymologically, it is the 'power to gather everything into the center.' This imagery is vital for understanding why Koreans view focus not just as a fleeting state of mind, but as a cultivated strength or muscle.

Academic Context: In South Korea's highly competitive education system, this word is used daily. Teachers and parents often discuss a student's '집중력' more than their innate intelligence. It is believed that while IQ is fixed, '집중력' can be trained through discipline and environment.
Workplace Performance: In the office, '집중력' is synonymous with productivity. A manager might praise an employee for having '대단한 집중력' (incredible focus) during a tight deadline. It implies not just being busy, but being effective.
Mental Health & Wellness: Recently, with the rise of digital distractions, the term is frequently used in discussions about 'digital detox' and mindfulness. People talk about their '집중력이 흐트러지다' (focus becoming scattered) due to smartphone notifications.

시험 기간에는 높은 집중력이 필수적입니다. (During exam periods, high concentration is essential.)

그 선수는 경기 막판에 놀라운 집중력을 보여주었습니다. (That athlete showed amazing concentration at the end of the match.)

Culturally, the concept of '집중력' is tied to the idea of 'Jung-shin-ryeok' (mental power). It is often portrayed in Korean media as a heroic trait. In K-Dramas, you might see a protagonist studying in a crowded library, completely oblivious to the noise around them; this is the physical manifestation of high 집중력. It is also a common marketing term for supplements, desk chairs, and lighting systems designed to help students study better. Understanding this word gives you a window into the Korean value of perseverance and mental discipline.

커피는 일시적으로 집중력을 높여줍니다. (Coffee temporarily increases concentration.)

아이들의 집중력 시간은 성인보다 짧습니다. (Children's concentration spans are shorter than adults'.)

명상은 집중력 향상에 큰 도움이 됩니다. (Meditation is a great help in improving concentration.)

Using 집중력 correctly requires understanding its relationship with specific verbs and particles. Because it is a noun representing an 'ability,' it most frequently appears with verbs that describe the state, movement, or manipulation of that ability. The most common verb pairings are 높이다 (to raise/increase), 떨어지다 (to fall/decrease), 기르다 (to cultivate/grow), and 발휘하다 (to demonstrate/exhibit).

Subject vs. Object: When 집중력 is the subject (e.g., 'Focus is good'), use the particle 이/가: '집중력이 좋다.' When it is the object (e.g., 'I improve my focus'), use 을/를: '집중력을 높이다.'

오후가 되니 집중력이 급격히 떨어졌어요. (As it became afternoon, my concentration dropped sharply.)

In formal settings, such as a report or a news broadcast, you will often see it combined with '향상' (improvement) or '결여' (lack). For example, '집중력 향상을 위한 프로그램' (A program for the improvement of concentration). In casual conversation, people might say '집중력이 짱이다' (Your focus is the best/awesome) to compliment someone who is deeply immersed in their work.

Describing Intensity: Use adjectives like '뛰어난' (outstanding), '놀라운' (amazing), or '부족한' (insufficient) to describe the quality of someone's 집중력.

그는 뛰어난 집중력으로 문제를 해결했습니다. (He solved the problem with outstanding concentration.)

When discussing the duration of focus, the word '시간' (time) is often appended to create '집중력 시간' (concentration span). For instance, '나의 집중력 시간은 30분 정도이다' (My concentration span is about 30 minutes). This is a very natural way to express how long you can stay focused.

어떻게 하면 집중력을 기를 수 있을까요? (How can I cultivate my concentration?)

소음 때문에 집중력이 분산되네요. (My concentration is being scattered because of the noise.)

Common Verb: 발휘하다: '발휘하다' (to exhibit/display) is often used in high-stakes situations like sports or exams. '결정적인 순간에 집중력을 발휘하다' (To show focus at the decisive moment).

You will encounter 집중력 in various high-pressure and self-improvement environments in Korea. It is a word that carries significant weight in a culture that prizes diligence and academic success. If you are in Korea, you'll hear it in the following places:

Hagwons (Private Academies): Teachers frequently use this word to motivate students. You'll hear phrases like '집중력 잃지 마세요!' (Don't lose your focus!) during long evening classes. Hagwon advertisements often claim their methods 'increase concentration by 200%'.
Sports Commentaries: During a baseball game or an archery match (a sport Korea excels in), commentators will emphasize '집중력의 싸움' (a battle of concentration). When a player makes a mistake, they might say '집중력이 조금 아쉬웠습니다' (Their concentration was a bit lacking/unfortunate).
Product Marketing: Walking through a store like Olive Young or a pharmacy, you'll see supplements (like red ginseng) or essential oils that promise '집중력 강화' (concentration strengthening). Even specialized desks called '독서실 책상' (study room desks) are marketed based on their ability to block distractions and improve focus.

뉴스 리포터: '수험생들에게 가장 필요한 것은 체력과 집중력입니다.' (News Reporter: 'The most necessary things for examinees are physical strength and concentration.')

In the workplace, during performance reviews or team meetings, a supervisor might mention '집중력' when discussing why a project succeeded or why errors occurred. It is a more professional and polite way to address someone's attention to detail than saying they were 'lazy' or 'careless.'

의사: '충분한 수면은 집중력 유지에 필수적입니다.' (Doctor: 'Sufficient sleep is essential for maintaining concentration.')

광고: '이 음악은 당신의 집중력을 두 배로 높여줍니다.' (Ad: 'This music doubles your concentration.')

For English speakers, the most common mistake is confusing the noun 집중력 (the ability) with the noun 집중 (the act of focusing). While they are related, they are not interchangeable in every context.

Mistake 1: Using 집중력 when you mean the act: Incorrect: '집중력을 하세요.' (Do concentration power.) Correct: '집중하세요.' (Focus.) You cannot 'do' 집중력; you 'have' it or 'improve' it.
Mistake 2: Incorrect Particle Usage: Learners often say '집중력이 높아요' when they mean they are focusing right now. '집중력이 좋다' describes a general trait. If you want to say you are focusing well at this moment, use '집중이 잘 돼요' (Focusing is going well).

틀린 문장: 나는 집중력을 했어요. (Incorrect: I did concentration power.)

옳은 문장: 나는 공부에 집중했어요. (Correct: I focused on my studies.)

Another mistake is using '집중력' when '주의력' (attention/attentiveness) is more appropriate. While similar, '주의력' is often used in a medical or safety context (like ADHD or driving safety), whereas '집중력' is about the intensity of mental effort on a task.

Mistake 3: Overusing the word 'Power': English speakers might try to translate 'concentration power' literally. In Korean, '집중력' is just one word. Don't try to add '힘' (power) to it; the '력' (力) already means power.

틀린 표현: 집중력 힘. (Incorrect: Concentration power power.)

To truly master 집중력, you should know how it compares to its synonyms and related terms. Each has a slightly different shade of meaning.

집중 (Jip-jung): This is the act of focusing. While '집중력' is the ability, '집중' is the action. Example: '집중이 안 돼요' (I can't focus/Focus isn't happening).
주의력 (Ju-ui-ryeok): Often translated as 'attentiveness.' It's the ability to pay attention to details and avoid mistakes. It is more about being 'careful' than 'intense.'
몰입 (Mor-ip): This means 'immersion' or 'flow.' It is a deeper state than just concentration. When you are in '몰입,' you lose track of time and self.

비교: 집중력은 능력이고, 몰입은 상태입니다. (Comparison: Concentration is an ability, and immersion is a state.)

Another word you might hear is '전념' (Jeon-nyeom), which means 'devoting oneself' to something. This is often used for long-term goals rather than short-term tasks. '학업에 전념하다' means to devote oneself entirely to one's studies over a long period.

아이의 주의력 결핍을 걱정하는 부모들이 많습니다. (Many parents worry about their child's lack of attentiveness/ADHD.)

그 작가는 창작 활동에 전념하고 있습니다. (The author is devoting himself to creative activities.)

よくある間違い

집중력을 해요. → 집중을 해요. / 집중해요.
You cannot 'do' an ability. You perform the action of focus (집중), but you possess the ability of focus (집중력).
집중력이 있어요. → 집중력이 좋아요.
While '있어요' is grammatically okay, Koreans almost always use '좋다' (good) or '대단하다' (great) to describe having focus.
집중력를 높이다. → 집중력을 높이다.
집중력 ends in a consonant (ㄱ), so the object particle must be '을', not '를'.
집중력이 떨어졌어요 (meaning I'm not interested). → 흥미가 떨어졌어요.
집중력 is about the mental capacity to focus, not the emotional interest (흥미).
Pronouncing it as Jip-Jung-Ryeok. → Jip-Jung-Nyeok.
The 'r' sound changes to 'n' due to the preceding 'ng' sound. This is a mandatory phonological rule.

ヒント

Particle Choice

Always check if your verb is an adjective (like 좋다) or an action verb (like 높이다) to choose the right particle for 집중력.

The Nasalization

Practice saying 'Jung-Nyeok' slowly. If you say 'Jung-Ryeok' with a hard 'R', it will sound very unnatural to Koreans.

Education Context

If you are a student in Korea, expect to hear this word constantly. It's the #1 trait teachers look for.

Hanja Roots

Remembering that 'Ryeok' (力) means power will help you learn dozens of other Korean words like 체력, 실력, and 노력.

Focus vs Ability

Don't say '집중력 하세요'. That's like saying 'Do focus power'. Say '집중하세요' for the command.

Concentration Span

Use '집중력 시간' when talking about how long you can study. It's a very common phrase.

Professionalism

Using '집중력' in a meeting sounds much more professional than saying you were 'listening' or 'working hard'.

Intensifiers

Add '초' (super/ultra) to make '초집중력' when you want to describe a state of extreme, almost superhuman focus.

Avoid Literal Translation

Don't say '집중 힘'. Even though 'Ryeok' means power, '집중력' is the fixed word for concentration power.

Visualizing

Visualize a laser beam. A laser is 'gathered' light. That is exactly what '집중력' is for your mind.

暗記しよう

記憶術

Think of 'Jip' as a ZIP file where you 'gather' all your thoughts. 'Jung' is the JUNGLE of information you are in the middle of. 'Ryeok' is the ROCKET power you need to stay focused.

視覚的連想

Imagine a magnifying glass (집중력) focusing sunlight (your thoughts) into a single bright point (the task) on a piece of paper.

Sino-Korean

文化的な背景

Be careful not to sound like you are judging someone if you say their 집중력 is low; it can be taken as a criticism of their effort or character.

While English speakers use 'focus' as both a verb and noun, Koreans use '집중력' specifically for the capacity, which is a more formal and clinical-sounding concept.

The 'Gong-bu-ga-meo-ni' (Study is everything) mindset in Korean dramas. Korean archers in the Olympics often credit their gold medals to '집중력' training. The book 'Flow' by Mihaly Csikszentmihalyi is very popular in Korea under the title '몰입', which is the ultimate form of 집중력.

よくある質問

10 問

You can say '집중이 안 돼요' (Focus isn't happening) or '집중을 못 하겠어요' (I can't do focus). Using '집중력' in this case sounds a bit more like you are complaining about your innate ability: '집중력이 떨어졌어요' (My focus power has dropped).

Yes, ADHD is often called '주의력 결핍 과잉행동 장애' in Korean, but in casual talk, people say '집중력이 부족하다' to describe the symptoms. It's a very common term in medical and parental discussions.

The most direct opposite is '산만함' (distractedness/scatteredness). If you want to say someone lacks focus, you say '집중력이 없다' or '산만하다'.

Yes, you can. For example, '사냥할 때 고양이의 집중력은 대단하다' (A cat's concentration when hunting is amazing). It applies to any being showing sustained attention.

It depends on the verb. Use '이' with '좋다', '나쁘다', '떨어지다'. Use '를' with '높이다', '기르다', '발휘하다'. Think: 'Is the focus doing something (이) or am I doing something to the focus (를)?'

In Korean phonology, when a syllable ending in 'ㅇ' (ng) is followed by 'ㄹ' (r), the 'ㄹ' changes to 'ㄴ' (n). This makes it easier to flow between the nasal 'ng' and the next sound. So, 'jung-ryeok' becomes 'jung-nyeok'.

Not really. For focusing on a person or a relationship, words like '일편단심' (one-hearted devotion) or '전념' are better. '집중력' is more for tasks and mental efforts.

You can say '집중력이 정말 좋으시네요!' (Your concentration is really good!) or '집중력이 대단하시네요!' (Your concentration is amazing!).

Not necessarily, but in Korea, they are highly correlated in people's minds. A person with high 집중력 is often seen as someone who will eventually become smart or successful because they can study effectively.

Koreans often recommend blue-backed fish (omega-3), nuts (walnuts look like brains!), and red ginseng (Hong-sam) for improving 집중력.
