Grammar Rule in 30 Seconds
Use -는 법이다 to express that something is a natural, inevitable, or universal truth.
- Attach -는 법이다 to verb stems: 먹다 → 먹는 법이다 (It is natural to eat).
- Use for universal truths: 사람은 누구나 실수하는 법이다 (Everyone is bound to make mistakes).
- Avoid for specific, one-time events; it implies a general rule of life.
Overview
In Korean, the -는 법이다 (neun beobida) grammar pattern is used to express a universal truth, a natural law, or an inevitable outcome. It asserts that something is bound to happen not as a mere prediction, but as a consequence of an established principle or the fundamental order of things. The core of this pattern is the noun 법 (beop), which literally translates to “law,” “rule,” or “method.” By attaching this to a verb or adjective clause, you elevate a statement from a simple observation to a declaration of objective certainty.
It’s the linguistic equivalent of stating, “It is a law of nature that...” or “It is an undeniable principle that...”
This pattern carries a formal, often philosophical tone, suggesting a degree of wisdom or deep understanding. It implies that the stated outcome is not random but follows a logical and predictable sequence based on a given condition. For example, 시간이 지나면 상처는 아물는 법이다 (With time, wounds are bound to heal) doesn’t just mean “the wound will probably heal.” It means that the healing of wounds over time is a fundamental principle of life, as certain as gravity.
Mastering -는 법이다 allows you to articulate cause and effect with a high degree of authority and nuance, moving beyond simple factual statements to express the underlying logic of the world.
How This Grammar Works
-는 법이다 is a type of predicative noun phrase. It combines a clause that modifies the noun 법 with the copula 이다 (to be). The full structure is [Condition/Action Clause] + 는 or (으)ㄴ + 법 + 이다.-는 법이다 part delivers the inevitable result. Its function is to generalize a specific event or tendency into an unbreakable rule.노력하면 (if one tries), sets the stage. The noun 법 (beop) acts as the anchor, framing the outcome not as a possibility but as a rule.이다, confirms this rule. So, in 노력하면 실력은 느는 법이다 (If you put in the effort, your skills are bound to improve), you are not just hoping for improvement. You are stating that the connection between effort and improved skill is a reliable, law-like principle.칭찬을 받으면 기분이 좋아지는 법이다 (It's natural to feel good when you receive a compliment).Formation Pattern
-는 법이다 depends on the type of predicate ending the clause. The rules are consistent and must be followed precisely. Pay close attention to the distinction between action verbs and descriptive verbs (adjectives).
-는 법이다 to the verb stem, regardless of whether it ends in a vowel or a consonant.
가다 (to go) → 가는 법이다
먹다 (to eat) → 먹는 법이다
-(으)ㄴ 법이다.
ㄹ (which is dropped), add -ㄴ 법이다.
-은 법이다.
예쁘다 (to be pretty) → 예쁜 법이다
멀다 (to be far) → 먼 법이다 (irregular: ㄹ is dropped)
작다 (to be small) → 작은 법이다
있다 / 없다 and -었- / -겠-
있다 (to exist) and 없다 (to not exist) are conjugated like action verbs, always taking -는 법이다.
재미있다 (to be interesting) → 재미있는 법이다
이유가 없다 (to have no reason) → 이유가 없는 법이다
-었- and future marker -겠- also follow the action verb rule, taking -는.
성공했던 사람도 실패하는 법이다 (Even people who were successful are bound to fail sometimes.)
-이다 and conjugate it as an adjective. This results in -(이)ㄴ 법이다. This form is less common and is typically used when defining the essential nature of something.
학생 (student) → 학생인 법이다 (This is grammatically possible but often sounds more natural as 학생은 공부하는 법이다 - A student is bound to study.)

Common Mistakes
-는 법이다 by misjudging its specific nuance and tone. Here are the most common errors to avoid.-는 법이다 for a personal plan. This pattern is for general truths, not specific, individual actions.- Incorrect:
*저는 내일 부산에 가는 법이에요.(I am bound to go to Busan tomorrow.) - Why it's wrong: Your trip to Busan is a personal decision, not a law of the universe. It sounds arrogant and bizarre, as if your travel plan is a cosmic inevitability.
- Correct:
저는 내일 부산에 갈 거예요.(I will go to Busan tomorrow.)
-기 마련이다-는 법이다 is stronger and more objective. -기 마련이다 points to a natural tendency or an expected outcome, especially regarding human emotions or common situations, while -는 법이다 refers to a fixed law or logical rule.- -는 법이다: Emphasizes a rigid, objective law. Best for logic, physics, or strong cause-and-effect.
올라간 것은 내려오는 법이다.(What goes up is bound to come down.) - -기 마련이다: Emphasizes a natural, expected tendency. Better for human behavior, emotions, or predictable but not absolute situations.
오래 안 보면 보고 싶어지기 마련이다.(It's natural to miss someone if you don't see them for a long time.)
-는 법이다 for the second example (보고 싶어지는 법이다) sounds a bit too strong, as if missing someone is a physical law rather than a natural emotion.~는 법이야 is common, using it for trivial matters can make you sound preachy or condescending. Its inherent weight requires a situation that merits aFormation Table
