Parisian who God inspires to be noble (7)
I believe the answer is:
marquis
'noble' is the definition.
(marquis is a kind of noble)
'parisian who god inspires' is the wordplay.
'parisian who' becomes 'qui' ('who' in French).
'god' becomes 'mars' (Mars is an example).
'inspires' is an insertion indicator (inspire means to breathe in).
'qui' placed inside 'mars' is 'MARQUIS'.
'to be' acts as a link.
(Other definitions for marquis that I've seen before include "Queensberry's rank" , "toff" , "De Sade's noble rank" , "Continental aristocrat" , "Nob" .)
