Lady R may suggest an isolated place (9)
I believe the answer is:
backwater
'isolated place' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
(Other definitions for backwater that I've seen before include "Place where no development happens" , "Isolated place" , "place of inactivity" , "Stagnant part of a river" , "in the sticks" .)
