Okay kiddo, let me try to explain this in a way that you can understand!
Xposé is a word that means to reveal or uncover something. When we use this word, we are usually talking about exposing something that was hidden or unknown before.
For example, let's say you are playing hide and seek with your friends. If your friend is hiding behind a tree and you notice them there, you might yell out "I see you! You've been xposéd!" This means that you have revealed their hiding spot and they are no longer hidden.
In the grown-up world, xposé is often used to describe investigative journalism. This means that reporters or journalists might spend a lot of time researching and uncovering information about a person or organization, and then they will publish this information for the public to see. When they do this, they are exposing something that was previously unknown or hidden.
So, does that make sense? Xposé means revealing something that was hidden before, like during a game of hide and seek or when journalists uncover important information about people or organizations.
