Educate artist in money (5)
I believe the answer is:
train
'educate' is the definition.
('train' can be a synonym of 'educate')
'artist in money' is the wordplay.
'artist' becomes 'ra' (Royal Academician, member of Royal Academy of Arts).
'in' is an insertion indicator.
'money' becomes 'tin' (I've seen this before).
'ra' going into 'tin' is 'TRAIN'.
(Other definitions for train that I've seen before include "Rail service" , "Means of transport or long tail on dress" , "one thing after another" , "Engine and carriages" , "Instruct - exercise" .)
