Replacement brings comfort (6)
I believe the answer is:
relief
I believe this is a double definition.
'replacement' is the first definition.
(thesaurus)
'comfort' is the second definition.
(relief is a kind of comfort)
'brings' is the link.
(Other definitions for relief that I've seen before include "Pleasure at removal of anxiety" , "Removal of distress" , "Alleviation or support" , "Easement from pain or stress" , "Sort of map" .)
