Unusual perception shown during service break (7)
I believe the answer is:
respite
'break' is the definition.
(respite is a kind of break)
'unusual perception shown during service' is the wordplay.
I cannot really see how this works, but
'perception' could be 'esp' (I have seen 'Extrasensory perception ' mean 'esp' so perhaps 'perception' could also mean 'esp') and 'esp' is located in the answer.
'service' could be 'rite' (a religious service) and 'rite' is found within the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for respite that I've seen before include "Pause from pain" , "Short let-up" , "A lull" , "Abatement, rest" , "Period of temporary relief" .)
