A2 adjective #2,000 mais comum 6 min de leitura

자신 있다

At the A1 level, you can think of '자신 있다' as a simple way to say 'I can do it well.' You might use it for basic skills like 'I am confident in Korean' (한국어에 자신 있어요) or 'I am confident in cooking' (요리에 자신 있어요). At this stage, focus on the 'Noun + 에 자신 있어요' pattern. It is a great way to express your interests and strengths to new friends. Just remember that it is the opposite of '자신 없어요' (I'm not confident). You don't need to worry about complex grammar yet; just use it to show your positive attitude toward learning!
At the A2 level, you start to use '자신 있다' to describe your plans and intentions. You will learn the pattern '-(으)ㄹ 자신 있다', which allows you to say things like 'I am confident I can pass' (합격할 자신 있어요). You also begin to see it used as an adjective to describe people, like '자신 있는 사람' (a confident person). This level is about moving beyond simple nouns and starting to link the word to actions. You should also be careful with the particle '에' and avoid using the object particle '을/를' which is a common mistake for beginners.
At the B1 level, you use '자신 있다' in more nuanced social and professional contexts. You might use it during a job interview to highlight your specific strengths: '저는 문제 해결에 자신 있습니다' (I am confident in problem-solving). You also start to recognize the difference between '자신' (the feeling) and '자신감' (the noun for confidence). You can express varying degrees of confidence using adverbs like '꽤' (quite), '전혀' (not at all - with 자신 없다), or '무척' (very). You understand that this phrase carries a sense of 'readiness' and 'preparedness' rather than just a vague feeling.
At the B2 level, you can distinguish '자신 있다' from similar words like '당당하다' (to be dignified/confident in manner) or '확신하다' (to be certain of a fact). You use '자신 있다' to discuss psychological states and self-efficacy. You might use it in writing to describe a character's development or in a debate to assert your position. You are comfortable with various endings like '-거든요' (because...), '-잖아요' (you know...), or '-다면서요?' (I heard that...) combined with '자신 있다'. You also understand the cultural nuance of when to be '자신 있다' and when to be humble.
At the C1 level, you use '자신 있다' with high precision in academic or professional discourse. You might analyze the '자신감' (self-confidence) of a demographic or discuss how '자신 있는 태도' (a confident attitude) affects leadership. You understand idiomatic expressions and can use the phrase in complex sentence structures, such as '자신 있다고 해서 반드시 성공하는 것은 아니다' (Just because one is confident doesn't mean they will necessarily succeed). You can also use it sarcastically or to question someone's overconfidence (자만심).
At the C2 level, you have a native-like grasp of the philosophical and psychological implications of '자신'. You can discuss the etymology (자신 - self-belief) and how it relates to Korean social structures. You can use the phrase in creative writing to evoke specific moods or in high-level negotiation where the subtle expression of confidence can change the outcome. You are aware of how the phrase has evolved in modern slang or how it is used in classical literature to describe a hero's resolve. Your usage is indistinguishable from a highly educated native speaker.

자신 있다 em 30 segundos

  • 자신 있다 means 'to be confident' and is used to express belief in one's skills or a successful outcome in various situations.
  • It is grammatically an adjective in Korean, often used with the particles '에' for subjects or '-(으)ㄹ' for actions.
  • Commonly heard in interviews, sports, and K-dramas, it signifies a proactive and positive mindset toward challenges and personal growth.
  • It is the opposite of '자신 없다' and should not be confused with '자만' (arrogance) or '확신' (factual certainty).

The Korean expression 자신 있다 (jasin itda) is a foundational adjective-phrase that translates to "to be confident" or "to have confidence." It is composed of the noun 자신 (self-confidence/oneself) and the existential adjective 있다 (to exist/to have). In the Korean mindset, confidence isn't just an abstract feeling; it is something you 'possess' or 'have within you.' This phrase is used to describe a state where an individual feels certain about their abilities, a specific outcome, or the truth of a statement. It is a highly positive and proactive term, often used in job interviews, sports, and personal development contexts to signal readiness and self-assurance.

Core Concept
The internal possession of certainty regarding one's own skills or a future result.
Grammatical Function
Functions as an adjective (descriptive verb), requiring '이/가' for the subject of confidence or '에' for the object of confidence.
Emotional Nuance
Conveys a sense of reliability, boldness, and psychological preparedness.

"저는 이번 시험에 정말 자신 있어요." (I am really confident about this exam.)

— Example of academic confidence

Understanding '자신 있다' requires looking at how Koreans view the 'self' (자). It is not just about ego, but about the alignment of one's preparation and one's belief. When you say you have '자신', you are telling the listener that your internal state is stable and prepared for the challenge ahead. It is the opposite of 자신 없다 (to lack confidence).

"요리라면 제가 가장 자신 있는 분야예요." (If it's cooking, that's the field I'm most confident in.)

Subjective vs Objective
While '확신하다' (to be sure) is often about facts, '자신 있다' is about personal capability.

"그는 자신 있는 목소리로 대답했다." (He answered in a confident voice.)

Using 자신 있다 correctly involves mastering three primary grammatical structures. Each structure changes the focus of what you are confident about. Because it ends in '있다', it follows the conjugation rules of adjectives in Korean, meaning in the present tense plain form, it remains '자신 있다' (unlike verbs which take -ㄴ/는다).

1. Noun + 에 자신 있다

This is the most common way to express confidence in a specific subject, skill, or field. The particle 에 marks the area of expertise.

  • 수학에 자신 있어요. (I am confident in math.)
  • 발표에 자신 있어요. (I am confident in presentations.)

2. Verb + -(으)ㄹ 자신 있다

When you want to say you are confident in your ability to *perform* an action, you use the prospective modifier -(으)ㄹ. This is equivalent to saying "I am confident that I will [verb]" or "I am confident to [verb]."

"혼자서도 잘 해낼 자신 있어요." (I am confident I can do it well even by myself.)

3. As a Noun Modifier (자신 있는)

To describe a person or an action as 'confident', you change '있다' to '있는'. This is frequently used with nouns like '태도' (attitude), '모습' (appearance/image), or '목소리' (voice).

Formal Setting
In interviews: "무엇이든 배울 자신 있습니다!" (I am confident I can learn anything!)
Casual Setting
With friends: "나 진짜 자신 있어!" (I'm really confident!)

You will encounter 자신 있다 in almost every facet of Korean life, from high-stakes business meetings to casual conversations about hobbies. It is a keyword in the Korean 'can-do' spirit (할 수 있다 정신).

In K-Dramas and Movies

In dramas, this phrase is often used by the protagonist to show growth. A character who was once timid might finally say, "이제는 자신 있어요" (I'm confident now). It's also a staple in romantic scenes where someone might say they are confident in their feelings: "너를 행복하게 해 줄 자신 있어" (I'm confident I can make you happy).

"사랑받을 자신 있어요?" (Are you confident you can be loved?)

In Variety Shows and Sports

In shows like 'Running Man' or 'Physical: 100', contestants are constantly asked, "자신 있습니까?" (Are you confident?). The typical energetic response is "자신 있습니다!" accompanied by a determined gesture. It signifies competitive spirit.

In the Workplace

During performance reviews or project pitches, expressing confidence is crucial. However, Korean culture also values humility, so '자신 있다' is often balanced with '최선을 다하겠습니다' (I will do my best).

Even though 자신 있다 seems straightforward, learners often trip over particles and nuances. Here are the most frequent pitfalls:

1. Using the Wrong Particle

Many learners try to use the object particle 을/를 because they think of 'confidence' as an object they are 'having'. However, because '있다' is an adjective in Korean grammar, it cannot take an object. You must use 에 or 이/가.

  • ❌ 한국어를 자신 있어요. (Incorrect)
  • ✅ 한국어에 자신 있어요. (Correct)

2. Confusing '자신' with '자기'

'자기' (jagi) also means 'self', but it is a pronoun. '자신' (jasin) can be a pronoun but also means 'confidence'. You cannot say '자기 있다' to mean 'I am confident'.

3. Overusing it in Humble Contexts

While it's good to be confident, saying "자신 있어요" too much about small things might sound arrogant (거만하다) in certain traditional Korean social circles. It's often better to say "열심히 해 보겠습니다" (I will try my best) if you want to sound more modest.

"너무 자신만만하면 실수하기 쉬워요." (If you are too full of confidence, it's easy to make a mistake.)

Nuance Check
자신 있다 is about the *feeling*. If you want to say someone *is* a confident person as a personality trait, '자신감이 넘치다' (to overflow with confidence) is more descriptive.

Korean has several ways to express certainty and assurance. Choosing the right one depends on whether you are talking about your skills, a fact, or a feeling of pride.

1. 자신감 (Jasingam) vs. 자신 (Jasin)

'자신감' is the noun for 'self-confidence'. You 'have' (있다) or 'lose' (잃다) 자신감. '자신 있다' is the adjective form. You use '자신감' when talking about the *concept* of confidence.

2. 확신하다 (Hwaksinhada)

This means 'to be certain' or 'to be sure' of a fact or a result. While '자신 있다' is internal and skill-based, '확신하다' is often based on evidence or strong belief in an external event.

"그가 성공할 것이라고 확신해요." (I am sure that he will succeed.)

3. 당당하다 (Dangdanghada)

This describes a 'confident and dignified' manner. It’s about how you carry yourself physically and socially. A person who stands tall and speaks clearly is '당당하다'.

Related Term
자부심 (Jabusim): Pride. Feeling confident because of your identity or achievements.
