Bounder understood to be a beastly boxer? (8)
I believe the answer is:
kangaroo
'bounder' is the definition.
(animal which bounds around)
'understood to be a beastly boxer?' is the wordplay.
I cannot really see how this works, but
'a' could be 'an' and 'an' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for kangaroo that I've seen before include "Aussie boxer" , "Marsupial from down-under" , "One bounces" , "Pouched animal" , "Marsupial (both parts 4's friends)" .)
