She has a title for bet after party (7)
I believe the answer is:
dowager
'she has a title' is the definition.
I can't tell whether this defines the answer.
'bet after party' is the wordplay.
'bet' becomes 'wager' (synonyms).
'after' is a charade indicator (letters next to each other).
'party' becomes 'do' (do is a kind of party).
'wager' after 'do' is 'DOWAGER'.
'for' is the link.
Can you help me to learn more?
(Other definitions for dowager that I've seen before include "Nobleman's widow" , "woman of status" , "Rich old woman" , "Widow, imposing elderly woman" , "Wealthy old woman" .)
