Clobber game when it retreats (4)
I believe the answer is:
garb
This clue might be a double definition.
'clobber game' is the first definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'it retreats' is the second definition.
The definition suggests a singular noun which matches the answer.
'when' acts as a link.
Can you help me to learn more?
(Other definitions for garb that I've seen before include "Distinctive dress of a group" , "costume" , "Outfit" , "Fashion of dress" , "Clothe" .)
