Artist exaggerating could make a cur artistic (12)
I believe the answer is:
caricaturist
'artist exaggerating' is the definition.
I can't judge whether this defines the answer.
'make a cur artistic' is the wordplay.
'make' indicates anagramming the letters.
'a'+'cur'+'artistic'='acurartistic'
'acurartistic' is an anagram of 'CARICATURIST'.
'could' acts as a link.
Can you help me to learn more?
(Other definitions for caricaturist that I've seen before include "One who lampoons" , "Producer of satirical portraits" , "Comic cartoonist" , "Artist producing comic portraits" , "Job sketching exaggerated facial features" .)
