Actress Sten (4)
I believe the answer is:
anna
'actress sten' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for anna that I've seen before include "Palindromic girl's name" , "Massey, Sewell or Karenina" , "Former Indian coin; girl's name" , "Girl - old Indian coin" , "Former one sixteenth of Rupee" .)
