Giverny painter (5)
I believe the answer is:
monet
'giverny painter' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for monet that I've seen before include "French impressionist (Waterlilies)" , "French artist shown in ..." , "Claude --, French impressionist painter" , "Met no impressionist painter" , "'Water Lilies' 13ac" .)
