I believe the answer is:

manet

I'm a little stuck... Click here to teach me more about this clue!

'artist' is the definition.
(I've seen this before)

I don't understand the rest of the clue.

(Other definitions for manet that I've seen before include "Edouard ___, painted Dejeuner sur l'herbe, d. 1883" , "Edouard -- (artist)" , "Olympia artist" , "Olympia painter" , "French painter" .)

I've seen this clue in The Times.
