Small ape (6)
I believe the answer is:
gibbon
'small ape' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for gibbon that I've seen before include "Ape -- author of the 14 15 of the 5 7" , "Asia's native" , "MONKEY" , "Animal" , "an eighteenth-century author" .)
