-(이)란

N(이)란 picks out a concept that you are about to define or explain the essence of: "N is (by its nature)…", "what we call N is…".

조사Particles

Han: (이)란 introduces a concept to be defined; to say what a particular person is doing these days, use the ordinary topic marker 은/는.

Examples

친구란 힘들 때 곁에 있어 주는 사람이다.A friend is someone who stays by your side when things are hard.
인생이란 원래 뜻대로 되지 않는 법이다.Life, by its nature, doesn't go the way you want.
행복이란 과연 무엇일까요?What, really, is happiness?
민주주의란 국민이 나라의 주인이 되는 정치 제도를 말한다.Democracy refers to a political system in which the people are the masters of the country.

Don’t mix up

-(이)란vsN은/는은/는 is a neutral topic marker for any statement; (이)란 is chosen when you define the concept itself: 물은 차가워요 vs 물이란 생명의 근원이다.
-(이)란vsN(이)라는 N(이)라는 (or its short form 이란) modifies the next noun, "called X"; definitional (이)란 ends the phrase as a topic: 김민수라는 사람 vs 교사란 학생을 가르치는 사람이다.
-(이)란vsN(이)야말로(이)야말로 stresses that X, above all others, fits the claim; (이)란 explains what X is: 건강이야말로 가장 중요하다 vs 건강이란 몸과 마음이 편안한 상태이다.

How to build it

N (consonant)+이란
N (vowel)+란

사랑 → 사랑이란, 친구 → 친구란

  1. Use it for general concepts and their definition or essence (사랑, 인생, 교육). For the current state or action of a specific person or thing, use 은/는 instead.
  2. The predicate usually states a definition or general truth: N이다, -는 것이다, -(으)ㄴ/는 법이다, -을/를 말한다, or a question such as 무엇일까요?
  3. It is typical of writing, speeches and reflective talk; in light everyday chat it can sound overly serious.
  4. Don't confuse it with 이란 directly before a noun (김민수란 사람), which is a shortened 이라는 meaning "called, named".
