Range in the Arabian desert (5)
I believe the answer is:
andes
'range' is the definition.
(Andes is an example)
'in the arabian desert' is the wordplay.
'in' indicates a hidden word.
'ANDES' is hidden in the letters of 'arabian desert'.
(Other definitions for andes that I've seen before include "The range of llamas?" , "Peak District" , "World's longest mountain range" , "danes found in mountains" , "Danes in S American mountains" .)
