Attentive artist's place in America (8)
I believe the answer is:
studious
'attentive' is the definition.
(thesaurus)
'artist's place in america' is the wordplay.
'artist's place' becomes 'studio' (I can't explain this - if you can you should give a lot more credence to this answer).
'in america' becomes 'U.S.' ('U.S.' is part of 'america').
'studio'+'us'='STUDIOUS'
Can you help me to learn more?
(Other definitions for studious that I've seen before include "reading a lot" , "Academic, diligent" , "Given to serious reading" , "Thoughtful - hard-working" , "Like a good schoolboy" .)
