Fight for which a ring is needed (10)
I believe the answer is:
engagement
'fight' is the definition.
(I know that fight can be written as engagement)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for engagement that I've seen before include "Betrothal; appointment" , "calls for signs of commitment" , "Commitment to marriage" , "Date, battle, or betrothal" , "Action necessary for breach" .)
