余命

1. Origins, structure, and basic meaning

• Structure: 余命 is read as よめい and is a noun for the remaining period a person is expected to live.
• Basic usage: Use 限られた余命 for a limited remaining lifespan and 余命の見通しを説明する for explaining its outlook.

2. Common pitfalls and similar expressions

• Kind of remaining time
  • It specifically concerns time left to live, not spare time before an ordinary deadline.
• Uncertain outlook and sensitivity
  • 見通し is a prognosis or outlook rather than a fixed date, and 慎重に説明する reflects the sensitivity of communicating it.
