Plunders shelves where solution half-hidden (8)
I believe the answer is:
ransacks
'plunders' is the definition.
('ransack' can be a synonym of 'plunder')
'shelves where solution half-hidden' is the wordplay.
I cannot really understand how this works, but
'solution' could be 'ans' (abbreviation for answer) and 'ans' is found within the answer.
The remaining letters 'racks' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for ransacks that I've seen before include "Takes as spoils" , "Rifles" , "Pillages or searches roughly" , "Plunders, loots" , "Plunders and pillages" .)
