make the arrangements
1. To organize, plan, or prepare what is necessary (for or to do something). Our legal team has already made the arrangements, so everything should be ready for you when you arrive on Monday. It will take me a little bit of time to make the arrangements, but the new equipment should be ready sometime in the next week or two.
2. To organize everything that is necessary for a funeral. I'm so shaken from her death that I can't even think about making the arrangements right now. My brothers and sisters and I all made the arrangements together when our father finally passed away.
make the arrangements
Euph. to arrange a funeral. A funeral services practitioner will be happy to help you make the arrangements. When my father died, I was the one who made the arrangements.
