Kangaroo, perhaps, or cad (7)
I believe the answer is:
bounder
'cad' is the definition.
(I know that cad can be written as bounder)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for bounder that I've seen before include "Dishonourable man (dated colloq.)" , "Untrustworthy type (once)" , "A cad - or a kind of jumper" , "despicable man" , "The skipper" .)
