Bounder that may supply angora, OK? (8)
I believe the answer is:
kangaroo
'bounder' is the definition.
(animal which bounds around)
'that may supply angora ok?' is the wordplay.
'that may supply' indicates anagramming the letters (the letters can supply other words).
'angora'+'ok'='angoraok'
'angoraok' with letters rearranged gives 'KANGAROO'.
(Other definitions for kangaroo that I've seen before include "Bounding marsupial" , "one jumps" , "impromptu kind of court" , "One's jumpy" , "Progress with poor clutch control" .)
