person going away; departing person
Literary or classical term for someone who is leaving or has left. Not used in casual conversation.
Classical expression for past times or things that have passed. Often contrasted with 来者 (らいしゃ, 'the future' or 'those who come').
See also: 来者 (らいしゃ)
I recalled a line from an old Chinese poem about seeing off a departing person.
There is a saying: 'Look to the past to know the future.'
