永眠

1. Origins, structure, and basic meaning

• Structure: 永眠 is read as えいみん and functions as a noun or with する as a solemn euphemism comparing death to eternal sleep.
• Basic usage: Use 静かに永眠する for a peaceful passing and 永眠した年 for the recorded year of death.

2. Common pitfalls and similar expressions

• Euphemism for death
  • It does not describe continuing ordinary sleep; it avoids a blunt statement of death and shows respect for the deceased.
• Suitable register
  • It fits solemn contexts such as a family-witnessed passing or a gravestone record rather than everyday descriptions of sleeping.
