Immoral to have drunken smooch with artist (6)
I believe the answer is:
rakish
'immoral' is the definition.
Both the answer and definition are adjectives. Maybe they are linked in a way I don't understand?
'drunken smooch with artist' is the wordplay.
'drunken smooch' becomes 'kish' (I can't justify this - if you can you should believe this answer much more).
'with' is a charade indicator (letters next to each other).
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'kish' after 'ra' is 'RAKISH'.
'to have' acts as a link.
Can you help me to learn more?
(Other definitions for rakish that I've seen before include "Dashing, devil-may-care" , "abandoned" , "Jaunty and irresponsible" , "Jaunty; fast-looking (boat)" , "Dapper" .)
