Okay, so you know how some people live in houses, right? Imagine that instead of a house, they live inside a bigger place. This bigger place has a fence all around it, and nobody can get in or out without permission. This is what we call an enclave.
Now, there are some people who live in an enclave in a country called Cyprus. They are called Greek Cypriots, and they have been living inside this enclave for a really long time.
The reason they can't leave is because their enclave is located in a part of Cyprus that is controlled by a different group of people who don't really like the Greek Cypriots. These people also control the borders, which means they get to decide who can come and go.
So even though the Greek Cypriots want to leave and visit other places, they can't because they are trapped inside the enclave. It's like they are stuck in a big, fenced-in area with no way out.
It's not really fair, and a lot of people are working to try and change the situation so that the Greek Cypriots can have more freedom and move around more. But for now, they are still enclaved and can't go wherever they want.
