"Been" and "gone" are both forms of the verb "go," but they are used in slightly different ways.
The main difference is that "been" is used to describe someone's past experience of going somewhere, while "gone" is used to describe someone's current absence from a place.
Here are some examples to help illustrate the difference:
• "I have been to Paris." This means that at some point in the past, the speaker traveled to Paris and has since returned. They are now present and talking about their past experience.
• "He has gone to Paris." This means that the person in question is currently in Paris and is not present with the speaker.
In summary:
• "Been" refers to past experience of going somewhere.
• "Gone" refers to current absence from a place.
