Clobber Christopher! (3)
I believe the answer is:
kit
This clue might be a double definition.
'clobber' is the first definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'christopher' is the second definition.
(short for Christopher)
Can you help me to learn more?
(Other definitions for kit that I've seen before include "Equipment, clothing" , "Necessary equipment" , "Football top, shorts, stockings and boots?" , "Outfit" , "Specialised clothing or set of parts for assembly" .)
