The Old South (5)
I believe the answer is:
dixie
'the old south' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for dixie that I've seen before include "Seceding states" , "Southern states that seceded from the USA in 1861" , "Southern states of USA - and a rousing song" , "Confederate US states" , "Pan" .)
