Impressionist painter Claude (5)
I believe the answer is:
monet
'impressionist painter claude' 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 "Giverny painter" , "Met no impressionist painter" , "French impressionist (Waterlilies)" , "French landscape painter" , "Claude, impressionist painter, d. 1926" .)
