Okay kiddo, the North/South Ministerial Council is a fancy name for a group of important people who work for both Northern Ireland and the Republic of Ireland. They all sit together to talk about things that affect both countries.
They meet regularly to make sure everyone is working together, sharing ideas and helping each other out. They talk about lots of different things like health, education, transportation, and lots more.
The council is made up of important politicians and leaders from both sides of the border. That way they can all work together to make sure things run smoothly and everyone is happy. This is important because Northern Ireland and the Republic of Ireland used to have big problems with each other, but now they are working together to make things better for everyone.
