Ban second spinner
I believe the answer is:
stop
'ban' is the definition.
(I've seen this in another clue)
'second spinner' is the wordplay.
'second' becomes 's' (common abbreviation).
'spinner' becomes 'top' (a spinning top).
's'+'top'='STOP'
(Other definitions for stop that I've seen before include "break" , "Pack it in - bar" , "Intercept" , "set of organ pipes" , "Put an end to" .)
