Cold alleviated and stopped (6)
I believe the answer is:
ceased
'stopped' is the definition.
('cease' can be a synonym of 'stop')
'cold alleviated' is the wordplay.
'cold' becomes 'c' (abbreviation, eg on taps).
'alleviated' becomes 'eased' ('ease' can be a synonym of 'alleviate').
'c'+'eased'='CEASED'
'and' acts as a link.
(Other definitions for ceased that I've seen before include "Stopped, quitted" , "Stopped, desisted" , "Concluded" , "Finished" , "Terminated" .)
