Pig-headed person's name for the kinkajou! (5)
I believe the answer is:
potto
'the kinkajou' is the definition.
('potto' can be a synonym of 'kinkajou')
'pig-headed person's name' is the wordplay.
'pig-headed person' becomes 'p' (I am not sure about this - if you are sure you should believe this answer much more).
'name' becomes 'otto' (Otto is an example).
'p'+'otto'='POTTO'
'for' is the link.
Can you help me to learn more?
(Other definitions for potto that I've seen before include "Sort of 13 [LEMUR]" , "Kinkajou" , "Slow-moving African" , "Little creature" , "Nocturnal primate" .)
