Did you know?

  • The noun 철 used in this phrase is a homonym that also means 'season'. To 'grow up' is conceptually linked to the arrival of the correct season for something to happen.
  • The phrase 철 좀 들어 is almost never used toward a superior or older person, as suggesting they lack maturity is considered a severe social transgression in Korea.
  • A common variation, 철이 없다, meaning 'to not have maturity', is often used as a playful or endearing way to describe a 'kid at heart' adult, depending on the tone.
