longevity; prolonging life
A somewhat formal or literary term for extending one's lifespan or the state of living long. Often used in contexts like health, medicine, or traditional practices.

長寿 is the common, everyday word for 'longevity'. 延齢 is more formal and emphasizes the act of extending life rather than just the state of living long.
延命 also means 'prolonging life', but is more commonly used in medical or clinical contexts (e.g., life-prolonging treatment). 延齢 has a slightly more traditional or holistic nuance.
Compound of 延 (prolong, extend) and 齢 (age, years). The exact historical derivation is uncertain, but the word is formed from kanji with clear meanings related to extending one's years.
