Fur shared by a couple of orangutangs (6)
I believe the answer is:
angora
'fur' is the definition.
The answer and definition can be both animals as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'shared by a couple of orangutangs' is the wordplay.
I cannot quite understand how this works, but
'a' could be 'an' and 'an' is present in the answer.
'of' could be 'o' and 'o' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
(Other definitions for angora that I've seen before include "Yarn or fabric made from goat hair" , "Fur of rabbit - hair of goat" , "Fine wool from certain goats" , "Fine yarn from hair of goats" , "Fabric made from goat or rabbit hair" .)
