Camel with one hump (9)
I believe the answer is:
dromedary
'camel with one hump' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for dromedary that I've seen before include "Kind of camel" , "One-humped camel bred for riding" , "Animal" , "desert transport" , "Arab racer" .)
