Titled widow (7)
I believe the answer is:
dowager
'titled widow' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for dowager that I've seen before include "Nobleman's widow" , "Woman who holds title from dead husband" , "Wordage (anag.)" , "Dignified (or wealthy) elderly woman" , "Important widow" .)
