Clever person packaged undergarment? (8)
I believe the answer is:
brainbox
'clever person' is the definition.
(I've seen this before)
'packaged undergarment?' is the wordplay.
I cannot really see how this works, but
'undergarment?' could be 'bra' (bra is a kind of undergarment) and 'bra' is found in the answer.
The remaining letters 'inbox' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for brainbox that I've seen before include "Einstein?" , "Very clever figure" , "Clever type" , "Egghead" , "Very clever person" .)
