It's more pleasant back in the precinct (5)
I believe the answer is:
nicer
'it's more pleasant' is the definition.
('nice' can be similar in meaning to 'pleasant')
'back in the precinct' is the wordplay.
'back' says the letters should be written in reverse.
'in' says the answer is hidden in the clue.
'recin' can be found hidden inside 'precinct'.
'recin' written backwards gives 'NICER'.
(Other definitions for nicer that I've seen before include "better" , "more likeable" , "harder to please" , "comparatively agreeable" , "it's more appealing" .)
