Art gallery (4)
I believe the answer is:
tate
'art gallery' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tate that I've seen before include "Art gallery benefactor" , "Well-known London art gallery" , "Modern and Britain galleries in London" , "Maurice - - , cricketer 1895-1956" , "Art Gallery donor" .)
