Does having two wines back-to-back take energy? (3,4)
I believe the answer is:
red deer
'does having two wines' is the definition.
I can't judge whether this defines the answer.
'back-to-back take energy?' is the wordplay.
'back-to-back' becomes 'redder' (I can't justify this - if you can you should believe this answer much more).
'take' indicates putting letters inside.
'energy?' becomes 'e' (physics symbol as in E=mce).
'redder' going around 'e' is 'RED DEER'.
Can you help me to learn more?
(Other definitions for red deer that I've seen before include "Large cervine animal" , "Large-antlered animal" , "Large grazing animal of temperate Europe and Asia" , "Common stag or hind" , "wild creature" .)
