With sentimental words, perhaps, passes on nice things (7)
I believe the answer is:
goodies
'nice things' is the definition.
(I've seen this before)
'with sentimental words perhaps passes' is the wordplay.
'with' is a charade indicator (letters next to each other).
'sentimental words perhaps' becomes 'goo' (goo can mean sentimentality).
'passes' becomes 'dies' (passes away).
'goo'+'dies' is 'GOODIES'.
'on' is the link.
(Other definitions for goodies that I've seen before include "Heroes; desirable items (informal)" , "Informally, nice people or edibles" , "Treats" , "nice things" .)
