Monday energy is problematic for hardworking person (6)
I believe the answer is:
dynamo
'hardworking person' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'monday energy is problematic' is the wordplay.
'monday' can be anagrammed to 'DYNAMO'.
Though, I'm not sure how this is indicated.
'for' is the link.
Can you help me to learn more?
(Other definitions for dynamo that I've seen before include "Converter of mechanical to electrical energy" , "Monday (anag)" , "Live wire" , "Producer of electrical energy" , "Machine" .)
