At the A1 level, '불합리적인' (bul-hap-ri-jeok-in) is a very advanced word that you might not need to use yourself, but you might see it in simple news headlines or hear it in dramas. It means 'unreasonable' or 'not fair.' Think of it as a very fancy way to say 'No' or 'Bad logic.' At this stage, just remember that '불' (bul) often means 'not.' So, '불-합리' means 'not-reasonable.' If you see a price that is way too high, like a bottle of water for $100, that is '불합리적인 가격' (an unreasonable price). You don't need to worry about the grammar too much yet, just recognize that it is a negative word used for things that don't make sense. It's much longer than basic words like '나빠요' (it's bad), so when you hear it, you know someone is talking about a serious problem. Most A1 learners will find '말도 안 돼요' (it doesn't make sense) much easier to use, but knowing '불합리적인' will help you understand when people are complaining about rules in Korea.
For A2 learners, '불합리적인' is a useful word to start recognizing in formal contexts. It is an adjective that describes a noun. You use it when a rule, a price, or a situation is not logical. For example, if your teacher gives you 1000 pages of homework for one night, you can say '이것은 불합리적인 숙제예요' (This is unreasonable homework). In Korean, many words are made of Hanja (Chinese characters). The '불' (bul) means 'not,' and '합리' (hap-ri) means 'rational' or 'reasonable.' The '-적인' (-jeok-in) part makes it an adjective, like adding '-al' in English (rational -> irrational). You will hear this word often in news clips about unfair companies or in dramas when the main character is fighting against a mean boss. It is more formal than '나쁜' (bad). If you use this word instead of '나쁜,' you sound much more educated and serious about your complaint. Practice by combining it with nouns like '규칙' (rule) or '상황' (situation).
At the B1 level, you should be able to use '불합리적인' in your own writing and speaking, especially when discussing social issues or workplace problems. You should understand the difference between the adjective form '불합리적인' and the predicate form '불합리하다.' For instance, '불합리적인 규칙을 바꿔야 해요' (We must change unreasonable rules) vs. '이 규칙은 불합리해요' (This rule is unreasonable). At this level, you can start to use it to express your opinion on more complex topics, like the cost of living or school policies. You should also notice the pronunciation change: because of the 'p' (ㅂ) and 'r' (ㄹ) meeting, it is pronounced as [불함니적인]. This is a key phonological rule for B1 learners to master. When you use this word, you are appealing to logic. It's a great word for debates. If someone makes a point that doesn't follow the facts, you can say '그것은 불합리적인 주장입니다' (That is an unreasonable/irrational argument). This shows you can handle formal vocabulary and abstract concepts.
B2 learners should have a nuanced understanding of '불합리적인' compared to similar words like '부당한' (unjust) and '비논리적인' (illogical). While '비논리적인' is strictly about the failure of logical steps, '불합리적인' often implies a social or systemic failure. For example, a '불합리적인 사회 구조' (unreasonable social structure) suggests that the way society is set up doesn't make sense for the people in it. At this level, you should use the word to critique systems and practices. You might use it in an essay about environmental policies or corporate ethics. You should also be comfortable using the adverbial form '불합리하게' to describe actions, such as '불합리하게 차별받다' (to be unreasonably discriminated against). Understanding the Hanja roots (不合理) will help you connect it to other words like '합리화' (rationalization) or '합리적' (rational). This level of vocabulary allows you to engage in sophisticated discussions about Korean society, particularly regarding the 'Hell Joseon' discourse or workplace 'Gab-jil' (power trips), where this word is a staple.
At the C1 level, '불합리적인' should be a natural part of your academic and professional lexicon. You should be able to identify its use in legal texts, editorial pieces, and high-level literature. You should understand how it functions in rhetorical structures to build a case against a specific policy or ideology. For instance, you might analyze how '불합리적인 관행' (unreasonable practices) are maintained through '합리화' (rationalization) by those in power. You should also be aware of the historical context of the word in Korean modernization, where the push for '합리성' (rationality) was a major theme. At this level, you can use the word to discuss philosophy or economics, such as '불합리적인 소비' (irrational consumption/spending). You should also be able to recognize when the word is being used sarcastically or as a form of social commentary in modern Korean literature. Your usage should be precise—knowing when to choose '불합리적인' over '모순적인' (contradictory) or '역설적인' (paradoxical) based on the specific type of logical failure you are describing.
For C2 learners, '불합리적인' is a word whose every nuance and colocation is mastered. You understand not just the word itself, but the entire semantic field surrounding rationality and irrationality in Korean thought. You can use it to engage in deep philosophical debates about the 'irrationality of existence' or to critique complex legal frameworks with precision. You are comfortable using it in the most formal settings, such as giving a speech at a conference or writing a legal brief. You also understand its weight in the 'minjung' (people's) movements and how it has been used to challenge authoritarian structures throughout Korean history. You can detect subtle shifts in meaning when the word appears in different registers—from a dry economic report to a passionate political manifesto. At this level, you might explore the concept of '불합리' as an existentialist theme in Korean art and film, comparing it to the 'Absurd' in Western philosophy. Your mastery is such that you can use the word to explain the most complex social phenomena, identifying the '불합리적인' elements of modern life with clarity and authority.

불합리적인 30秒で

  • Used to describe something illogical or unfair.
  • Common in formal, legal, and workplace contexts.
  • Derived from Hanja meaning 'not-fitting-reason'.
  • More formal than 'mal-do an-doe-neun' (nonsense).

The Korean adjective 불합리적인 (bul-hap-ri-jeok-in) is a powerful term used to describe situations, rules, or behaviors that lack logic, fairness, or common sense. Rooted in Hanja (Chinese characters), the word breaks down into Bul (不 - not), Hap (合 - to join/fit), and Ri (理 - reason/logic), followed by the suffix -jeok (적) which turns it into an attribute, and finally the adjective marker -in (인). Essentially, it describes something that does not 'fit with reason.' While English speakers might use 'unreasonable' or 'irrational' interchangeably, in Korean, this word often carries a heavy weight of social criticism, particularly regarding systemic issues or unfair corporate practices.

Formal Contexts
This word is frequently used in news reports, legal discussions, and academic papers to critique policies that are logically flawed or treat people unfairly. For example, a law that taxes the poor more than the rich would be described as 불합리적인.
Workplace Usage
In the Korean office environment, employees might use this word to describe 'Gab-jil' (abuse of power) or outdated hierarchies where junior staff are expected to do illogical tasks simply because a senior said so.
Societal Critique
Social movements often use this term to highlight systemic inequalities, such as gender-based wage gaps or unfair recruitment processes.

회사의 불합리적인 대우에 항의하기 위해 직원들이 모였습니다. (Employees gathered to protest against the company's unreasonable treatment.)

Understanding the nuance of this word requires recognizing that it isn't just about a person being 'annoying.' It is about a fundamental break in the link between action and logic. If you are asked to work overtime every day for no extra pay and no clear reason, that is a 불합리적인 situation. It challenges the 'rational' expectation of labor and compensation.

이것은 매우 불합리적인 결정이라고 생각합니다. (I think this is a very irrational decision.)

In everyday life, you might hear this word in dramas when a character is fighting against a corrupt system. It highlights the frustration of dealing with something that simply doesn't make sense from a moral or logical standpoint. It is a more sophisticated way of saying 'that's not right' or 'that's crazy' (말도 안 돼).

우리는 불합리적인 관습을 타파해야 합니다. (We must break down unreasonable customs.)

사회 전반에 퍼진 불합리적인 편견을 없애야 해요. (We need to eliminate unreasonable prejudices spread across society.)

To wrap up, 불합리적인 is your go-to word when you want to criticize something for being illogical, unfair, or nonsensical in a structured or formal way. It’s a key term for discussing social issues and workplace grievances in Korea.

Using 불합리적인 (bul-hap-ri-jeok-in) correctly involves understanding its grammatical role as an adjective that modifies nouns. Because it ends in '-in' (인), it is almost always followed immediately by a noun. If you want to use it as a predicate (to say 'It is unreasonable'), you would use the form 불합리하다 (bul-hap-ri-ha-da). Let's explore the various ways this word appears in sentence structures.

Modifying a Noun
Structure: [불합리적인] + [Noun]. This is the most common usage. It describes a specific object or concept as irrational. Example: 불합리적인 가격 (Unreasonable price).
As a Predicate
To say 'The situation is unreasonable,' use 불합리합니다 (formal) or 불합리해요 (polite). Example: 이 규칙은 너무 불합리해요 (This rule is too unreasonable).

그들은 불합리적인 요구를 계속하고 있습니다. (They are continuing to make unreasonable demands.)

When modifying abstract concepts like 'demands,' 'prices,' or 'rules,' the word highlights that these things do not follow common sense. In a professional setting, you might use it to discuss project timelines or budget constraints that are impossible to meet. It signals to the listener that the speaker finds the logic behind the matter to be faulty.

이러한 불합리적인 상황을 더 이상 참을 수 없어요. (I can no longer tolerate this unreasonable situation.)

In debate or argumentative writing, this word is a staple. It allows the writer to maintain a professional tone while delivering a sharp critique. Instead of saying 'This is bad,' saying 'This is a 불합리적인 policy' points to a specific failure of reasoning, which is more persuasive in a Korean context.

그의 주장은 불합리적인 근거에 기반하고 있습니다. (His argument is based on unreasonable/irrational grounds.)

Finally, consider the emotional weight. While it sounds academic, it is often used when someone feels a deep sense of injustice. Using it in a sentence like '불합리적인 차별' (unreasonable discrimination) combines logical critique with moral indignation.

우리는 불합리적인 제도 개선을 위해 노력해야 합니다. (We must work to improve unreasonable systems.)

과거의 불합리적인 관행들이 여전히 남아 있습니다. (Unreasonable practices from the past still remain.)

You will encounter 불합리적인 (bul-hap-ri-jeok-in) in various specific sectors of Korean life. It is not a word usually heard in casual banter between close friends at a bar—unless they are venting about their boss. Instead, it populates the worlds of news, law, corporate culture, and intellectual discourse. Let's look at the primary domains where this word thrives.

News and Media
Journalists use this word to describe government policies or corporate scandals. If a company is caught fixing prices, the news will describe the '불합리적인 가격 책정' (unreasonable pricing). It provides a veneer of objectivity while pointing out a clear wrong.
Legal and Political Dramas
In K-Dramas like 'Stranger' (Secret Forest) or 'Law School,' characters often fight against '불합리적인 법' (unreasonable laws) or '불합리적인 수사' (irrational investigations). It is a key word for the 'underdog' fighting the system.

뉴스는 불합리적인 세금 제도에 대해 보도했습니다. (The news reported on the unreasonable tax system.)

In the corporate world, this word is used during performance reviews or strategy meetings. If a manager sets a goal that is mathematically impossible to achieve, a brave employee might call it a '불합리적인 목표' (unreasonable goal). However, because Korean culture values hierarchy, this word is often used carefully or in anonymous forums like 'Blind' (an app for employees).

부장님의 지시는 정말 불합리적인 것 같아요. (I think the manager's instructions are really unreasonable.)

Educational settings also use this term. When students discuss historical events, they might talk about '불합리적인 신분 제도' (unreasonable caste systems) of the Joseon Dynasty. It helps students learn to look at history through the lens of logic and human rights. In university lectures, professors use it to describe theories that have been debunked or are logically inconsistent.

역사 속에는 많은 불합리적인 일들이 있었습니다. (There were many unreasonable things in history.)

Finally, in the context of consumer rights, you might see this word in reviews. If a hotel has a policy that doesn't allow check-ins after 6 PM but still charges full price, a customer might leave a review calling it a '불합리적인 규정' (unreasonable regulation). It is a formal way to complain that carries more weight than just saying 'I'm angry.'

이 계약서는 소비자에게 불합리적인 조항을 포함하고 있습니다. (This contract contains clauses that are unreasonable for the consumer.)

While 불합리적인 (bul-hap-ri-jeok-in) is a useful word, English speakers and even intermediate Korean learners often misuse it. The most common error is applying it to situations that are simply 'bad' or 'unpleasant' rather than truly 'illogical.' Let's break down the frequent pitfalls.

Confusing with '부당한' (Unjust)
While they overlap, '부당한' (bu-dang-han) focuses on fairness and rights, whereas '불합리적인' focuses on logic and reason. If you are fired for no reason, it is both. If a math problem is unsolvable, it is 불합리적인, but not necessarily 부당한.
Using it for People's Personalities
In English, we might say 'He is an unreasonable person' to mean he is stubborn. In Korean, calling a person '불합리적인 사람' sounds very formal and technical. It’s better to use '고집 센' (stubborn) or '말이 안 통하는' (someone you can't talk to) for personal traits.

❌ 그 친구는 정말 불합리적인 성격이에요. (That friend has a very unreasonable personality - sounds awkward/too formal.)

Another mistake is forgetting the difference between '불합리적인' (adjective) and '불합리하게' (adverb). Learners often use the adjective form where an adverb is needed. If you want to say 'He acted unreasonably,' you must use the adverbial form.

✅ 그는 불합리하게 행동했습니다. (He acted unreasonably.)

Learners also sometimes confuse it with '비논리적인' (illogical). While very similar, '비논리적인' (bi-non-ri-jeok-in) is strictly about the structure of an argument (A doesn't lead to B). '불합리적인' is broader and can include social systems, prices, and behaviors that don't make sense in a broader context.

이 논문은 비논리적인 결론을 내리고 있습니다. (This paper reaches an illogical conclusion - better than 불합리적인 here.)

Finally, avoid using it for trivial things. If your friend picks a restaurant you don't like, calling it '불합리적인 선택' (an unreasonable choice) is overly dramatic and sounds like you are writing a legal brief against them. For small things, use '별로인' (not great) or '이해가 안 가는' (doesn't make sense).

To truly master 불합리적인 (bul-hap-ri-jeok-in), you need to know its synonyms and how they differ in nuance. Korean has many ways to express 'unreasonableness,' and choosing the right one depends on whether you are focusing on logic, fairness, or common sense.

비논리적인 (Bi-non-ri-jeok-in)
Meaning: Illogical. Use this when the internal logic of a statement or theory is broken. It is more academic and less about social justice than 불합리적인.
부당한 (Bu-dang-han)
Meaning: Unjust or unfair. Use this when someone's rights are being violated or when a reward/punishment doesn't fit the action. It has a stronger moral tone.
말도 안 되는 (Mal-do an doe-neun)
Meaning: Nonsensical / 'Doesn't even make word.' This is the casual, everyday version. If a friend tells a crazy lie, you use this, not 불합리적인.

그것은 말도 안 되는 소리예요! (That's nonsense! - Casual/Natural)

When comparing 불합리적인 and 몰상식한 (mol-sang-sik-han), the latter means 'lacking common sense.' While '불합리적인' describes a system or decision, '몰상식한' is often used to describe a person's rude or ignorant behavior. For example, smoking in a non-smoking area is 몰상식한, but the law that allows it would be 불합리적인.

그의 행동은 정말 몰상식했습니다. (His behavior was truly lacking in common sense/rude.)

Another alternative is 억지스러운 (eok-ji-seu-reo-un), which means 'forced' or 'strained.' This is used when someone is trying too hard to make a point that doesn't fit, or when a movie plot feels unnatural. If a character suddenly changes personality for no reason, that's 억지스러운, whereas a rule that forbids breathing on Tuesdays is 불합리적인.

영화의 결말이 너무 억지스러웠어요. (The movie's ending was too forced.)

In summary, while '불합리적인' is your primary tool for critiquing illogical systems and formal decisions, having these alternatives allows you to express specific shades of 'wrongness' in different social contexts.

The term appears frequently in the writings of Korean existentialist authors. Used in the movie 'Parasite' to describe certain social structures. A common keyword in Korean labor union slogans.

よくある質問

10 問

You can, but it sounds very formal. Calling someone a '불합리적인 사람' means they make decisions that lack logic. For 'stubborn' or 'difficult,' use '고집 센' or '까다로운' instead.

Close, but not exactly. 'Unfair' is '불공평한' or '부당한'. '불합리적인' means it doesn't make sense logically. For example, a rule that everyone must wear hats indoors is '불합리적인' (unreasonable/illogical), even if it's '공평한' (applied to everyone equally).

The 'ㅂ' and 'ㄹ' meet and change. Pronounce it like '함니' (ham-ni). This is the most natural way.

Yes, but like many Sino-Korean words, the context might vary. In South Korea, it's very common in corporate and social criticism.

No, for a math error, use '틀린' (wrong) or '계산 착오' (calculation error). Use '불합리적인' for the *reasoning* behind a math problem if the problem itself is impossible to solve.

The direct opposite is '합리적인' (hap-ri-jeok-in), meaning reasonable or rational.

Be careful. It's a strong word. Use it to describe a 'situation' or 'system' rather than the boss's personal actions to avoid sounding rude.

The closest slang is '노답' (no answer/hopeless) or '어이없다' (to be dumbfounded).

Use '불합리하게' when you are describing a verb. For example: 'He was treated unreasonably' (불합리하게 대우받았다).

Yes! '합리화' (hap-ri-hwa) means rationalization. People often use '합리화' to try and justify '불합리적인' (unreasonable) actions.
