"Impression, Sunrise" painter (5)
I believe the answer is:
monet
'impression sunrise painter' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for monet that I've seen before include "'Water Lilies' 13ac" , "French landscape painter" , "Claude -, French artist" , "Claude ---, painter (waterlilies)" , "French artist shown in ..." .)
