Stop, you ruddy bore (7)
I believe the answer is:
endured
'bore' is the definition.
('endure' can be a synonym of 'bear')
'stop you ruddy' is the wordplay.
'stop' becomes 'end' ('end' can be a synonym of 'stop'**).
'you' becomes 'u' (I've seen this in other clues).
'ruddy' becomes 'red' ('red' can be a synonym of 'ruddy').
'end'+'u'+'red'='ENDURED'
(Other definitions for endured that I've seen before include "Borne" , "Patiently suffered" , "Put up with something" , "Bore or tolerated" , "Bore; put up with" .)
