Relaxed, or wound up, blowing top (5)
I believe the answer is:
eased
'relaxed' is the definition.
(I've seen this in another clue)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for eased that I've seen before include "Moved carefully" , "Alleviated" , "Oiled" , "Made less stressful or difficult" , "Relieved, mitigated" .)
