Welsh literature in English is like telling a story in a way that some people who live in Wales can understand, but in a language called English. People in Wales have their own special way of speaking and writing, but not everyone can understand it. So, some people who live in Wales write their stories in a different way, using English words so that more people can understand what they are saying. This is called Welsh literature in English! It's a way for people from Wales to share their stories with the world!
