Woman from the United Nations (4)
I believe the answer is:
edna
'woman' is the definition.
(woman's name)
'from the united nations' is the wordplay.
'from' says the answer is hidden in the clue.
'EDNA' can be found hidden inside 'united nations'.
(Other definitions for edna that I've seen before include "___ O'Brien, Irish novelist, b. 1930" , ". . . . O'Brien, ... Saint Vincent Millay" , "Dean (anag) - it's a girl's name!" , "Female name" , "Dame - Everage, housewife-superstar" .)
