寿命
How to Understand
寿 is a Chinese character meaning 'longevity' or 'age,' and 命 means 'life' or 'fate.' Together, 寿命 refers to the length of a person's or an object's life, typically used for living beings but sometimes applied to inanimate objects as well.
The character 寿 combines the radical for 'person' (亻) with the phonetic component 寸, which originally meant 'inch' or 'measure,' suggesting the idea of measuring a person's life. 命, on the other hand, contains the radical for 'person' and the phonetic component 令, reflecting its connection to life or fate.
寿命 is commonly used in medical or scientific contexts to describe how long something can last. It also appears in philosophical discussions about life and death. In everyday speech, it's often used to talk about the lifespan of animals, plants, or even technology.
