Painter in Stuttgart is troubled (6)
I believe the answer is:
artist
'painter' is the definition.
(painter is an example)
'in stuttgart is troubled' is the wordplay.
'in' indicates the answer is hidden within the clue.
'ARTIST' is hidden in the letters of 'stuttgart is troubled'.
(Other definitions for artist that I've seen before include "Bacon, for example?" , "Creator of aesthetic works" , "One skilled in creative works" , "Skilled person" , "A painter, sculptor or other creative person" .)
