Posture in second spell not right (6)
I believe the answer is:
'posture' is the definition.
(stance is a kind of posture)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for stance that I've seen before include "Position, viewpoint" , "One's physical or mental attitude" , "Attitude (of body, mind)" , "Pose, for a golfer say" , "Position of the body or an attitude" .)
