ELI5: Explain Like I'm 5

Apudessive case

The apudessive case is a fancy way of saying "next to" or "beside" something. It's like if you're playing with your toys and you have a toy car next to a toy fire truck. The apudessive case helps us say that the toy car is "next to" the toy fire truck. It's just a way to show where something is located in relation to something else.
