Woman identified by a US attorney (3)
I believe the answer is:
ada
'woman' is the definition.
(woman's name)
'a us attorney' is the wordplay.
'us attorney' becomes 'DA' (abbreviation for District Attorney).
'a'+'da'='ADA'
'identified by' is the link.
(Other definitions for ada that I've seen before include "Novel by Vladimir Nabokov" , "Programming language" , "-- Lovelace, pioneer in computing" , "Palindromic girl's name" , "Girl's name, one letter short of a man's name" .)
