In the countryside, artist breaking law no end (5)
I believe the answer is:
rural
'in the countryside' is the definition.
(I've seen this before)
'artist breaking law no end' is the wordplay.
'artist' becomes 'ra' (Royal Academician, member of Royal Academy of Arts).
'breaking' is an insertion indicator.
'law' becomes 'rule' (rule is a kind of law).
'no end' means to remove the last letter.
'rule' with its final letter taken off is 'rul'.
'ra' placed within 'rul' is 'RURAL'.
(Other definitions for rural that I've seen before include "Connected with farming" , "Bucolic; pastoral" , "Pastoral or agricultural" , "Countrified" , "Rustic" .)
