Song of the South (5)
I believe the answer is:
dixie
'south' is the definition.
(synonyms)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for dixie that I've seen before include "Army cooking pot - the southern states of the USA" , "Southern states that seceded from the USA in 1861" , "Southern states of USA - and a rousing song" , "Large iron cooking pot" , "South America's" .)
