Split decision? (7)
I believe the answer is:
divorce
This could be a double definition.
'split' is the first definition.
(divorcing is a kind of splitting)
'decision?' is the second definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for divorce that I've seen before include "Ending of marriage" , "Permanent separation" , "Split" , "End one's marriage" , "Get separated" .)
