Patient acceptance of suffering and misfortune (8)
I believe the answer is:
stoicism
'patient acceptance of suffering and misfortune' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for stoicism that I've seen before include "Uncomplaining fortitude" , "Behaviour enduring hardship" , "Quality of bearing hardship without complaining" , "Endurance of hardship without complaint" , "Patient acceptance of suffering and misfortune" .)
