Water-lily painter (5)
I believe the answer is:
monet
'water-lily painter' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for monet that I've seen before include "Claude, impressionist painter, d. 1926" , "Giverny painter" , "Claude --, French impressionist painter" , "he painted Rouen Cathedral" , "French impressionist (Waterlilies)" .)
