Capital person settled in manor (5)
I believe the answer is:
roman
'capital' is the definition.
(thesaurus)
'person settled in manor' is the wordplay.
'manor' anagrams to 'ROMAN'.
However, I am not clear how this is indicated.
Can you help me to learn more?
(Other definitions for roman that I've seen before include "French story" , "of foreign city" , "Does this citizen live in a manor?" , "Norma (anag) -- upright style of print" , "Style of upright type" .)
