Forbearance, stolidity (8)
I believe the answer is:
stoicism
I believe this is a double definition.
'forbearance' is the first definition.
(thesaurus)
'stolidity' is the second definition.
(I know that stolidity can be written as stoicism)
(Other definitions for stoicism that I've seen before include "Patient acceptance of suffering and misfortune" , "Indifference to pleasure or pain" , "Behaviour enduring hardship" , "Resignation" , "Impassivity, patience" .)
