Lull (7)
I believe the answer is:
respite
'lull' is the definition.
(I have seen 'A lull ' mean 'respite' so perhaps 'lull' could also mean 'respite')
This is the entire clue.
(Other definitions for respite that I've seen before include "Pause from exertion, etc" , "See trip (anag.)" , "temporary delay" , "Period of relief (from unpleasant thing)" , "Break from doing something" .)
