Relative squeezed energy out of juice? (4)
I believe the answer is:
dead
'out of juice?' is the definition.
'dead' can be an answer for 'out' (thesaurus). I'm unsure of the 'of juice?' bit.
'relative squeezed energy' is the wordplay.
I cannot quite see how this works, but
'energy' could be 'e' (physics symbol as in E=mc2) and 'e' is found in the answer.
'relative' could be 'dad' (dad is a kind of relative) and 'dad' is located in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for dead that I've seen before include "Defunct" , "Gone to meet one's Maker" , "Not quick" , "cold" , "No longer living" .)
