The artisan hides compassion (5)
I believe the answer is:
heart
'compassion' is the definition.
(I've seen this before)
'the artisan hides' is the wordplay.
'hides' indicates the answer is hidden within the clue.
'HEART' is hidden within 'the artisan'.
(Other definitions for heart that I've seen before include "Muscular organ - compassion" , "Decorated (cake)" , "Not a club" , "Centre; valour" , "bottle" .)
