What would you call someone that has died but got given a second chance? They are now alive. What would you call that person?
The person has been resurrected
Restore (a dead person) to life.
‘he queried whether Jesus was indeed resurrected’
As such, I would say that that person is a resurrectee
Revenant : one that returns after death or a long absence
The answers so far talk of second chances within the same life, but the adjective reincarnate can be used to describe someone who has died and been given a second chance through another life.
