After review rector accommodating a person who’s inventive (7)
I believe the answer is:
creator
'person who's inventive' is the definition.
(someone who creates or invents things)
'after review rector accommodating a' is the wordplay.
'after review' is an anagram indicator (letters reviewed or revised).
'accommodating' means one lot of letters goes inside another.
'rector' with letters rearranged gives 'cretor'.
'cretor' placed around 'a' is 'CREATOR'.
(Other definitions for creator that I've seen before include "Originator - God" , "Maker" , "The Almighty" , "Inventor" , "Person who makes or invents things" .)
