Gong brings many in to dinner, for example (5)
I believe the answer is:
medal
'gong' is the definition.
(I've seen this before)
'many in to dinner for example' is the wordplay.
'many' becomes 'd'.
'in' is an insertion indicator.
'to dinner for example' becomes 'meal' (dinner is a kind of meal).
'd' put inside 'meal' is 'MEDAL'.
'brings' acts as a link.
(Other definitions for medal that I've seen before include "Decorative award" , "sort of play" , "Decoration, award" , "Gong (sl.)" , "Religious or commemorative pin" .)
