Duck giving doctor a form of energy (5)
I believe the answer is:
drake
'duck' is the definition.
(drake is a male duck)
'doctor a form of energy' is the wordplay.
I cannot quite understand how this works, but
'doctor' could be 'dr' (abbreviation) and 'dr' is found in the answer.
'a' is present in the answer.
'energy' could be 'ke' (K.E. is an example) and 'ke' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'giving' acts as a link.
Can you help me to learn more?
(Other definitions for drake that I've seen before include "might be after a duck?" , "adventurer from Devon" , "Particular kind of duck" , "Ship" , "Explorer" .)
