noun
long time; long years of service
Refers to a long period of time, often in the context of someone's experience or tenure. The term is somewhat literary and not commonly used in everyday conversation.
彼は劫臈を経た職人だ。
He is a craftsman with many years of experience.
劫臈を重ねた味わいがある。
It has a flavor that comes from long aging.
The term 劫臈 combines 劫 (kalpa, an immensely long period in Buddhist cosmology) and 臈 (year-end sacrifice, later associated with years of service or age). The exact historical derivation is uncertain, but the compound conveys the idea of a very long time or seasoned experience.
