Might hear before bed if they're to get a bye, reportedly, after this temporary interval (4)
I believe the answer is:
lull
'interval' is the definition.
(I know that lull is a type of break)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for lull that I've seen before include "Put to sleep - respite" , "A quiet interlude as in storm" , "Calm interval in storm" , "A quiet spell as in a storm" , "Short spell of calm" .)
