Land us and reorder (5)
I believe the answer is:
sudan
'land' is the definition.
(Sudan is an example)
'us and reorder' is the wordplay.
'reorder' is an anagram indicator (I've seen this in other clues).
'us'+'and'='usand'
'usand' anagrammed gives 'SUDAN'.
(Other definitions for sudan that I've seen before include "Sun ad for the African state" , "Country W. of Ethiopia" , "Us and the African state" , "Country in NC Africa, capital Khartoum" , "African nation" .)
