Etymology
Origin of interact
Explanation
Talking, dancing, playing a game — all of these activities allow you to interact with other people. To interact means to communicate and react to the people you're involved with. Some video games are called interactive because they are not static, like board games, but allow players to interact with them and direct the story. If you are talking about chemicals or medicines that interact, the presence of one affects the way the other works. If someone says that you interact well with children, it means you communicate well with them and they respond to you.
