Weary? Get a blanket (4)
I believe the answer is:
pall
This clue is a double definition.
'weary?' is the first definition.
('pall' can be a synonym of 'weary')
'a blanket' is the second definition.
(thesaurus)
'get' is the link.
(Other definitions for pall that I've seen before include "Become boring and uninteresting" , "tedious here" , "wear off" , "Cloth over a coffin - become insipid" , "Cloth to cover a coffin" .)
