Skilled in getting artist productive (6)
I believe the answer is:
arable
'productive' is the definition.
(similar in meaning)
'skilled in getting artist' is the wordplay.
'skilled in' becomes 'able' (I can't justify this - if you can you should believe this answer much more).
'getting' indicates putting letters inside.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'able' placed around 'ra' is 'ARABLE'.
Can you help me to learn more?
(Other definitions for arable that I've seen before include "Ploughland" , "agricultural land" , "Land for ploughing" , "Suitable for ploughing" , "Of land, capable of growing crops" .)
