Boffin whose brains might be scrambled? (7)
I believe the answer is:
'boffin' is the definition.
(I've seen this before)
'brains might be scrambled?' is the wordplay.
I cannot quite see how this works, but
'be' could be 'head' (heading is a kind of being) and 'head' is present in the answer.
The remaining letters 'egg' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'whose' is the link.
Can you help me to learn more?
(Other definitions for egghead that I've seen before include "An intellectual (inf.)" , "Very clever person" , "Brainiac" , "brain" , "Informal intellectual of ovoid type" .)
