Taken from cover and shot (7)
I believe the answer is:
shelled
'taken' is the definition.
(shelling is a kind of taking)
'cover and shot' is the wordplay.
I cannot really see how this works, but
'cover' could be 'shell' (shell is a kind of cover) and 'shell' is found in the answer.
The remaining letters 'ed' 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).
'from' acts as a link.
Can you help me to learn more?
(Other definitions for shelled that I've seen before include "Bombed" , "Under cannon fire" , "Deprived of casing" .)
