Destroy with moving victory at beginning of winter (8)
I believe the answer is:
decimate
'destroy' is the definition.
(I've seen this before)
'moving victory at beginning of winter' is the wordplay.
I cannot really understand how this works, but
'at' is present in the answer.
The remaining letters 'decime' 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).
'with' acts as a link.
Can you help me to learn more?
(Other definitions for decimate that I've seen before include "Reduce greatly (by 10%?) in number" , "Kill one in ten (as Romans did as punishment for mutiny)" , "Medicate (anag.)" , "severely cut" , "By killing" .)
