An interruption during the play (4-3)
I believe the answer is:
time-out
'an interruption' is the definition.
(I know that time out is a type of interruption)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for time-out that I've seen before include "Short rest break" , "Brief break in play in a game" , "Respite" , "Period for recreation or rest" , "Rest period as in basketball" .)
