The artisan hides his compassion (5)
I believe the answer is:
heart
'his compassion' is the definition.
'heart' can be an answer for 'compassion' (I've seen this in another clue). I'm not sure about the 'his' bit.
'the artisan hides' is the wordplay.
'hides' says the answer is hidden in the clue.
'HEART' is hidden within 'the artisan'.
Can you help me to learn more?
(Other definitions for heart that I've seen before include "Crux" , "one needs to beat" , "Red card" , "Blood-pumping organ" , "Not a club" .)
