Pals out of range (4)
I believe the answer is:
alps
'range' is the definition.
(mountain range)
'pals out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'pals' anagrammed gives 'ALPS'.
'of' acts as a link.
(Other definitions for alps that I've seen before include "high points" , "Swiss mountains" , "High mountains" , "European mountain range" , "South-central European mountain system" .)
