Scent a catastrophic position taken (6)
I believe the answer is:
stance
'position taken' is the definition.
(I've seen this before)
'scent a catastrophic' is the wordplay.
'catastrophic' indicates an anagram.
'scent'+'a'='scenta'
'scenta' with letters rearranged gives 'STANCE'.
(Other definitions for stance that I've seen before include "Bearing" , "Way of standing, like golfer addressing ball" , "Posture, standing position" , "Pose, for a golfer say" , "Position, viewpoint" .)
