Cohesion means holding things together or sticking to what's important.
Imagine you're working on a group project at school. You and your friends need to make sure everyone is pulling their weight and doing their part, so that you can all finish the project on time and it turns out great. This is an example of cohesion - when people work together and support each other to achieve a common goal.
