Resigned in disbelief at a list I circulated (10)
I believe the answer is:
fatalistic
'resigned' is the definition.
(I've seen this before)
'in disbelief at a list i circulated' is the wordplay.
'in' says the answer is hidden in the clue.
'FATALISTIC' is hidden in the letters of 'disbelief at a list i circulated'.
(Other definitions for fatalistic that I've seen before include "Believing in predestination" , "Accepting lot" , "Resigned" .)
