Rest of rules broken covering exit, oddly (7)
I believe the answer is:
leisure
'rest' is the definition.
(leisure is a kind of rest)
'rules broken covering exit oddly' is the wordplay.
'broken' indicates an anagram.
'covering' indicates putting letters inside.
'oddly' indicates alternate letters.
The alternate letters of 'exit' are 'ei'.
'rules' is an anagram of 'lsure'.
'lsure' placed around 'ei' is 'LEISURE'.
'of' is the link.
(Other definitions for leisure that I've seen before include "Time for relaxation and pleasure" , "Time available for ease and relaxation" , "Time to rest and enjoy" , "R&R" , "Rest, relaxation" .)
