Occupatio

Occupatio is a big fancy word that means "taking possession of something that doesn't belong to you."

Imagine if you go to a park and you see a toy that no one is playing with. If you take that toy and start playing with it, you are using occupatio.

But just because you take the toy, it doesn't mean that you get to keep it forever. If the owner of the toy shows up and tells you that it's theirs, you have to give it back to them.

So, in summary, occupatio is a way of taking something that doesn't belong to you, but it doesn't mean that you get to keep it forever.
