Start off fresh list (4)
I believe the answer is:
lean
'list' is the definition.
(thesaurus)
'start off fresh' is the wordplay.
'start off' means to remove the first letter (I've seen 'starting off' mean this (the starting letter is removed)).
'fresh' becomes 'clean' (I've seen this before).
'clean' with its first letter taken off is 'LEAN'.
(Other definitions for lean that I've seen before include "Incline, bend" , "Of meat, with little or no fat" , "Incline; (of person) thin" , "Tend towards being thin" , "Meagre" .)
