Revisited Sumerian land (8)
I believe the answer is:
suriname
'land' is the definition.
(Suriname is an example)
'revisited sumerian' is the wordplay.
'sumerian' anagrams to 'SURINAME'.
However, I'm not clear how the anagram is indicated.
Can you help me to learn more?
(Other definitions for suriname that I've seen before include "Turns out that US marine is in a South American state" , "Country" , "land" .)
