Bath Rome's set out in this place (8)
I believe the answer is:
somerset
'bath' is the definition.
Both the definition and answer are singular nouns.
Maybe there's an association between them I don't understand?
'rome's set out in this place' is the wordplay.
'set out' indicates an anagram.
'in' means one lot of letters goes inside another.
'this place' becomes 'set' (I've seen this before).
'romes' with letters rearranged gives 'omers'.
'omers' put inside 'set' is 'SOMERSET'.
Can you help me to learn more?
(Other definitions for somerset that I've seen before include "part of the west" , "cricket team" , "Street location" , "Mendip county; a London House" , "Rome's set up in this English county" .)
