Sense in keeping promises for a change (10)
I believe the answer is:
impression
'sense' is the definition.
(thesaurus)
'in keeping promises for a change' is the wordplay.
'keeping' is an insertion indicator.
'for a change' indicates anagramming the letters.
'promises' with letters rearranged gives 'mpressio'.
'in' placed around 'mpressio' is 'IMPRESSION'.
(Other definitions for impression that I've seen before include "Imitation (of a person)" , "opinion" , "Mark" , "Feeling; print" , "take-off" .)
