Shame men toyed with hidden souvenir (7)
I believe the answer is:
memento
'souvenir' is the definition.
(I know that souvenir can be written as memento)
'shame men toyed with hidden' is the wordplay.
'hidden' indicates a hidden word.
'MEMENTO' is hidden within 'shame men toyed with'.
(Other definitions for memento that I've seen before include "Reminder of a person or event" , "Something kept" , "This reminds" , "Keepsake or souvenir" , "Reminder that death is inevitable" .)
