Where one might find better Irish impressionist (6)
I believe the answer is:
renoir
'impressionist' is the definition.
(I have seen 'French Impressionist ' mean 'renoir' so perhaps 'impressionist' could also mean 'renoir')
'where one might find better irish' is the wordplay.
'where one might find better' becomes 'reno' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'irish' becomes 'IR' (abbreviation for Irish).
'reno'+'ir'='RENOIR'
Can you help me to learn more?
(Other definitions for renoir that I've seen before include "Pierre Auguste ---, painter; Jean ---, film-director" , "'No, I err, he was a painter (6)'" , "Fr. impressionist ('La Loge')" , "French impressionist painter, d. 1919" , "French artist" .)
