Pause for every plug (7)
I believe the answer is:
stopper
'plug' is the definition.
(I know that plug 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 "Perhaps cork" , "Cork - goalkeeper?" , "Bung" , "Plug for a bottle" , "Maybe cork" .)
