Every one of the old revolutionary Southern ways (6)
I believe the answer is:
alleys
'ways' is the definition.
(as in alleyways)
'every one of the old revolutionary southern' is the wordplay.
'every one of' becomes 'all'.
'the old' becomes 'ye'.
'revolutionary' is a reversal indicator.
'southern' becomes 's' (abbreviation).
'ye' in reverse letter order is 'ey'.
'all'+'ey'+'s'='ALLEYS'
(Other definitions for alleys that I've seen before include "Narrow passages between buildings - some cats frequent them" , "Back lanes" , "Narrow passages between streets" , "Laneways" , "Narrow passageways" .)
