Go out with anorak and jumper (8)
I believe the answer is:
kangaroo
'jumper' is the definition.
(animal which jumps)
'go out with anorak' is the wordplay.
'out with' indicates an anagram (out can mean wrong or inaccurate).
'go' mixed up with 'anorak' can make 'KANGAROO'.
'and' acts as a link.
(Other definitions for kangaroo that I've seen before include "Marsupial from down-under" , "Large Australian mammal" , "Antipodean marsupial" , "Jumping marsupial" , "The sort of court" .)
