Ring somebody at Kennington (4)
I believe the answer is:
oval
'kennington' is the definition.
I can't tell whether this defines the answer.
'ring somebody' is the wordplay.
'ring' becomes 'O' (O is the shape of a ring).
'somebody' becomes 'val' (I can't explain this - if you can you should give a lot more credence to this answer).
'o'+'val'='OVAL'
'at' acts as a link.
Can you help me to learn more?
(Other definitions for oval that I've seen before include "sports ground" , "6D 5A [TUBE STATION]" , "London cricket-ground" , "34 [CRICKETER] 's domain" , "not quite round" .)
