  • Biological lifespan: Talking about how long a person or animal lives.
  • Product lifespan: Referring to how long a device or product lasts before it needs replacement.

Collocations and Patterns

  • 수명 연장 (extension of lifespan): Used when discussing increasing life expectancy or product durability.
  • 평균 수명 (average lifespan): Commonly used in statistics or general statements about life expectancy.
  • 수명이 다 되다 (lifespan is over): A phrase often used when something has reached the end of its functional life.

Register and Usage Notes

'수명' is a neutral noun and can be used in both formal and informal contexts. It is common in scientific, medical, and everyday conversations.

Common Mistake

Learners sometimes confuse '수명' with '생명' (saengmyeong), which means 'life' in the sense of being alive or existence, rather than the length of life. Remember, '수명' focuses on duration, while '생명' focuses on the state of being alive.
