The place for riverside art? (4)
I believe the answer is:
tate
'riverside art?' is the definition.
The definition suggests a singular noun which matches the answer.
'the place' is the wordplay.
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'place' becomes 'ate' (I am not sure about this - if you are sure you should believe this answer much more).
't'+'ate'='TATE'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for tate that I've seen before include "Britain/Modern gallery" , "art patron" , "Old Poet Laureate" , "Art gallery founded by sugar magnate" , "One of four art galleries in England" .)
