Some sophisticated native woman (4)
I believe the answer is:
edna
'woman' is the definition.
(woman's name)
'some sophisticated native' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'EDNA' is hidden in the letters of 'sophisticated native'.
(Other definitions for edna that I've seen before include "Female name" , "Prolific Irish woman novelist . . . . O'Brien" , "Famous dame" , "___ O'Brien, Irish novelist, b. 1930" , ". . . . O'Brien, ... Saint Vincent Millay" .)
