Oscar winner Paquin (4)
I believe the answer is:
anna
'oscar winner paquin' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for anna that I've seen before include "was of very small account in India" , "Former one sixteenth of Rupee" , "Former Indian coin, girl" , "-- Wintour, editor" , "Unit of length" .)
