Call about energy profit recovery (9)
I believe the answer is:
regaining
'call about energy profit recovery' is the definition.
I can't tell whether this definition defines the answer.
'call about energy profit recovery' is the wordplay.
'call' becomes 'ring' (telephone call).
'about' indicates putting letters inside.
'energy' becomes 'e' (physics symbol as in E=mca).
'profit recovery' becomes 'gain' (I can't justify this - if you can you should give a lot more credence to this answer).
'e'+'gain'='egain'
'ring' going around 'egain' is 'REGAINING'.
Can you help me to learn more?
(Another definition for regaining that I've seen is " Getting back".)
