"Water Lilies” painter (5)
I believe the answer is:
monet
'water lilies 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 "French impressionist (Waterlilies)" , "'Water Lilies' 13ac" , "Claude ---, painter (waterlilies)" , "Giverny painter" , "Met no impressionist painter" .)
