Always cut Sweden out (4)
I believe the answer is:
ever
'always' is the definition.
('ever' can be a synonym of 'always')
'cut sweden out' is the wordplay.
'cut' becomes 'sever' (severing is a kind of cutting).
'sweden' becomes 's'.
'out' is a deletion indicator.
'sever' with 's' removed is 'EVER'.
(Other definitions for ever that I've seen before include "Eternity" , "Always, at any time" , "Always and permanent" , "Perpetually" , "Continuously" .)
