Rest in Leeds, travelling south (8)
I believe the answer is:
idleness
'rest' is the definition.
(thesaurus)
'in leeds travelling south' is the wordplay.
'travelling' indicates anagramming the letters.
'south' becomes 's' (abbreviation).
'in'+'leeds'='inleeds'
'inleeds' is an anagram of 'idlenes'.
'idlenes'+'s'='IDLENESS'
(Other definitions for idleness that I've seen before include "Disinclination to work" , "Reluctance to work" , "State of inactivity" , "Inactivity, indolence" , "Lazy behaviour" .)
