Pause for every bung (7)
I believe the answer is:
stopper
'bung' is the definition.
(I know that bung can be written as stopper)
'pause for every' is the wordplay.
'pause' becomes 'stop'.
'for every' becomes 'per' ('per' means 'for each' or 'for every').
'stop'+'per'='STOPPER'
(Other definitions for stopper that I've seen before include "One who checks" , "Cork - goalkeeper?" , "Plug - cork" , "Plug for a bottle" , "One blocks" .)
