Not specified (7)
I believe the answer is:
unnamed
'not specified' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for unnamed that I've seen before include "Not identified in mundane way" , "anon" , "without identification" , "Anonymous < nark wishes to be ____" , "Nude man (anag) - not identified" .)
