~기 마련이다
It is natural for something to happen.
Explanation at your level:
At this level, think of this as a way to say 'It is normal.' If you want to say 'It is natural to be tired,' you just say '피곤하기 마련이다.' Use it when you want to agree that something is expected.
You can use this to explain life patterns. For example, 'If you don't study, your grades will go down.' In Korean, you can say '공부를 안 하면 성적이 떨어지기 마련이다.' It makes your sentences sound much more fluent.
This is a great tool for giving advice. When a friend is sad about a breakup, you can say '시간이 지나면 잊히기 마련이야' (It is natural to forget as time passes). It shows you understand the natural flow of life.
Use this to sound more philosophical. It’s perfect for expressing that outcomes are inevitable. It adds nuance to your arguments, showing that you aren't just stating an opinion, but a general truth.
At the advanced level, you can use this to couch your observations in a more sophisticated tone. It is excellent for writing or formal speaking where you need to discuss trends or human behavior without sounding too aggressive.
Mastering this involves understanding the subtle difference between this and other 'inevitability' structures like ~게 되어 있다. While ~게 되어 있다 implies a system or external force, ~기 마련이다 implies a natural, almost emotional or universal truth. Use it to add cultural depth to your speech.

Hey there! Have you ever noticed how some things just always happen? Like, if you don't study, you'll probably get a bad grade, or if you go out in the rain without an umbrella, you'll get wet. In Korean, we use ~기 마련이다 to express this exact feeling of inevitability.
Think of it as the Korean way of saying 'it is bound to happen' or 'it is only natural.' It’s not just a guess; it’s a reflection of how the world works. When you use this structure, you are telling the listener that the outcome you are describing is the logical result of the situation.
It’s a super useful phrase for sharing wisdom or explaining patterns in life. Whether you're talking about human nature, weather, or daily habits, ~기 마련이다 adds that perfect touch of 'I told you so' or 'that's just life' to your sentences. It’s friendly, conversational, and makes you sound much more natural in your daily Korean chats!
The structure ~기 마련이다 is rooted in the noun 마련. Historically, 마련 refers to a 'plan,' 'preparation,' or 'arrangement.' When you say something is 마련이다, you are essentially saying that it is 'arranged' or 'prepared' by the nature of the situation itself.
Over time, the Korean language evolved to use this noun as a way to describe outcomes that feel 'pre-arranged' by fate or logic. It isn't a word that changed drastically in meaning, but rather a functional shift where a concrete noun became a grammatical tool for expressing causality.
Interestingly, this structure is purely Korean in origin. It doesn't rely on Sino-Korean roots, which gives it a very authentic and native feel. It connects deeply to the Korean cultural emphasis on 순리 (the natural order of things). By using this, you are tapping into a long tradition of observing the world and accepting its predictable rhythms.
You use ~기 마련이다 by attaching it to the stem of a verb. For example, if you want to say 'it is natural to be nervous,' you take the verb 떨다 (to tremble/be nervous), change it to 떨기, and add 마련이다 to get 떨기 마련이다.
It is most commonly used in neutral to slightly formal settings. You might hear it in advice columns, during deep conversations with friends, or in essays. It’s perfect for when you want to sound wise or empathetic. It’s not typically used in very rigid, stiff business reports, but it’s definitely not 'slang' either.
Common collocations often involve verbs related to human emotions or natural processes. You will often see it paired with words like 변하다 (to change), 힘들다 (to be hard), or 잊다 (to forget). It’s a great way to soften a critique or offer comfort by suggesting that the situation is normal and expected.
While ~기 마련이다 is a grammatical structure, it appears in many wise sayings. Here are five ways it shows up in common Korean thought:
- 실수하기 마련이다: Everyone makes mistakes; it's natural.
- 변하기 마련이다: People and things are bound to change over time.
- 잊히기 마련이다: Memories are bound to fade eventually.
- 힘들기 마련이다: New challenges are naturally difficult at first.
- 만나면 헤어지기 마련이다: The classic 'meeting leads to parting'—it's just the way of life.
These expressions highlight the philosophical nature of the phrase. Using these will make you sound like a native speaker who understands the deeper, poetic side of the Korean language.
Grammatically, this is very straightforward. You take the verb stem and add ~기 to turn it into a noun form, then attach 마련이다. There are no complex conjugations to worry about! It works with almost any action verb.
Pronunciation-wise, pay attention to the li-eul (ㄹ) sound. It’s pronounced 'ma-ryeo-ni-da.' The 'n' sound from the ni carries over smoothly. It should flow like one single block of sound rather than separate words.
There isn't a specific 'plural' form because it's a structural ending. In terms of stress, native speakers often put a slight emphasis on the word right before 마련이다 to highlight the cause. It’s a very rhythmic structure that sounds great in a sentence!
