Assumes energy should change in rubber? (8)
I believe the answer is:
masseuse
'rubber?' is the definition.
(I've seen this before)
'assumes energy should change' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'assumes' is 'masseus' which is present in the answer.
'energy' could be 'e' (physics symbol as in E=mc2) and 'e' is present in the answer.
No letters remain.
This explanation may well be incorrect...
'in' acts as a link.
Can you help me to learn more?
(Other definitions for masseuse that I've seen before include "Manipulator of body" , "She kneads bodies" , "Reliever of tensions in the body" , "Uses seam (anag)" , "Uses same sort of woman who kneads muscles to lessen stiffness" .)
