Angora OK to make a jumper? (8)
I believe the answer is:
kangaroo
'a jumper?' is the definition.
(animal which jumps)
'angora ok to make' is the wordplay.
'to make' is an anagram indicator.
'angora'+'ok'='angoraok'
'angoraok' anagrammed gives 'KANGAROO'.
(Other definitions for kangaroo that I've seen before include "Would oak groan badly under the weight of this animal" , "Would anorak go on the animal?" , "Jumper of grey or red" , "Large Australian mammel" , "Large Australian marsupial" .)
