Know, oddly, about wild angora jumper (8)
I believe the answer is:
kangaroo
'jumper' is the definition.
(I've seen this before)
'know oddly about wild angora' is the wordplay.
'oddly' means one should take alternating letters (letters in the odd-numbered positions are used).
'about' means one lot of letters goes inside another.
'wild' is an anagram indicator.
The alternating letters of 'know' are 'ko'.
'angora' anagrammed gives 'angaro'.
'ko' enclosing 'angaro' is 'KANGAROO'.
(Other definitions for kangaroo that I've seen before include "Unofficial court of law" , "Marsupial from down-under" , "One bounces" , "The sort of court" , "One's jumpy" .)
