Eased off (6)
I believe the answer is:
abated
'eased off' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for abated that I've seen before include "dropped off" , "Lessened" , "Slackened off, died back" , "Subsided or decreased like storm" , "Went down and calmed like stormed" .)
