Daughter interrupting dinner gong (5)
I believe the answer is:
medal
'gong' is the definition.
(I've seen this before)
'daughter interrupting dinner' is the wordplay.
'daughter' becomes 'd'.
'interrupting' indicates putting letters inside.
'dinner' becomes 'meal' (I've seen this in other clues).
'd' put into 'meal' is 'MEDAL'.
(Other definitions for medal that I've seen before include "Award for distinction" , "What an Olympic Games winner gets" , "Decorative award" , "Prize disc for as for Olympic Games win" , "Metal disc given as award" .)
