Okay kiddo, so imagine there are two groups of people. Some people like to buy things from other countries because it's cheaper or because they can't find it in their own country. But other people think it's important to protect their own country's businesses and workers by making it harder for people to buy things from other countries.
Now, a long time ago, most countries had rules that made it hard to buy things from other countries. But then after a big war, many countries agreed to be more friendly and work together. They wanted to make it easier for people to trade and do business with each other. This was called the "liberal" idea.
But some people were still worried that this would hurt their own country's businesses and workers. So they made some changes to the liberal idea. They said that it was okay to trade with other countries, but there should be some rules to protect their own country's businesses and workers. This was called "embedded liberalism" because they "embedded" some rules into the liberal idea.
So basically, embedded liberalism is when countries agree to trade and do business with each other, but they also have some rules to protect their own country's businesses and workers. It's like playing a game where everyone agrees to the rules, but some players get some extra special powers to protect themselves.
