Someone will give her another ring just before the match ... (5,2,2)
I believe the answer is:
Here is my best explanation:
'someone' is the definition.
(bride-to-be is a kind of someone)
'her another ring just before the match' is the subsidiary indication.
I cannot really understand how this works, but
'her' could be 'bride' and 'bride' is present in the answer.
'ring' could be 'o' and 'o' is present in the answer.
This explanation may well be incorrect...
'will give' is the link.
(Another definition for bride-to-be that I've seen is "Woman engaged (with a train?)".)
