Thinking debut requires one to conceal energy (7)
I believe the answer is:
opining
'thinking' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for opining that I've seen before include "Expressing one's view" , "Thinking" .)
I've seen this clue in The Independent.
Want a hint initially instead of a full solution?
