Electricity essential for this working meal? (5,9)
I believe the answer is:
power breakfast
'electricity essential for this working meal?' is the definition.
I know nothing about this answer so I can't judge whether this works.
'electricity essential for this working meal?' is the wordplay.
I cannot really understand how this works, but
'electricity' could be 'power' (I've seen this in another clue) and 'power' is found within the answer.
'meal?' could be 'breakfast' (breakfast is a kind of meal) and 'breakfast' is found in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for power breakfast that I've seen before include "summit early?" , "Influence, by chance, quick early business meeting" .)
