They wear shorts and pants (6)
I believe the answer is:
boxers
'they' is the definition.
Both the answer and definition are plural nouns.
Perhaps they are linked in a way I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for boxers that I've seen before include "Dogs; packers" , "Craters" , "in the ring with shorts" , "Dogs or pugilists" , "Pugs; dogs" .)
