Artist has subversive second americano at the Hermitage (6)
I believe the answer is:
ashram
'the hermitage' is the definition.
(I have seen 'Indian hermitage ' mean 'ashram' so perhaps 'hermitage' could also mean 'ashram')
'artist has subversive second americano' is the wordplay.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'has' is a charade indicator (letters next to each other).
'subversive' becomes 'ash' (I can't explain this - if you can you should believe this answer much more).
'second americano' becomes 'm' (snd letter of 'americano').
'ra' put after 'ash' is 'ashra'.
'ashra'+'m'='ASHRAM'
'at' acts as a link.
Can you help me to learn more?
(Other definitions for ashram that I've seen before include "religious community" , "Hindu retreat location" , "Place for religious retreat (in India)" , "spiritual centre?" , "Hindu religious retreat" .)
