Hated exam? Indeed (8)
I believe the answer is:
detested
'hated' is the definition.
(I know that hated can be written as detested)
'exam? indeed' is the wordplay.
I cannot really understand how this works, but
'exam?' could be 'test' ('test' can be a synonym of 'exam') and 'test' is located in the answer.
The remaining letters 'deed' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for detested that I've seen before include "Loathed over test deed" , "not at all popular" , "Despised" , "Cordially loathed" , "Couldn't stand trial" .)
