Example lacking in opinion (6)
I believe the answer is:
stance
'opinion' is the definition.
(thesaurus)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for stance that I've seen before include "Batsman's position" , "Way of standing, like golfer addressing ball" , "Pose, for a golfer say" , "position when batting" , "Posture; viewpoint" .)
