Less than pleased when relieved (5)
I believe the answer is:
eased
'relieved' is the definition.
(easing is a kind of relieving)
'less than pleased' is the wordplay.
'EASED' is hidden within the letters.
However, I'm uncertain how this is indicated.
'when' acts as a link.
Can you help me to learn more?
(Other definitions for eased that I've seen before include "Lessened, pain or discomfort, say" , "Slowed down" , "Made less stressful or difficult" , "Relaxed" , "Died down" .)
