Trouble in Naples is not hurting (8)
I believe the answer is:
painless
'not hurting' is the definition.
(I've seen this before)
'trouble in naples is' is the wordplay.
'naples is' anagrams to 'PAINLESS'.
But, I am not clear how this is indicated.
Can you help me to learn more?
(Other definitions for painless that I've seen before include "Trouble free" , "Easy - without suffering" , "Involving little effort; not hurting" , "Undemanding" , "Needing little effort" .)
