Okay little one, English-speaking world refers to all the places where people speak English. So just like how we speak English here in our home or school, there are other countries and places where people also speak English as their main language.
Some of those places include England, United States of America, Canada, Australia, New Zealand, Ireland, and some parts of the Caribbean. In these countries, English is the official language, which means it's used in government, schools, and businesses.
Now, there are also other countries where English is not the official language, but many people still speak it as their second language. For example, in India, many people speak English alongside Hindi or other regional languages.
So, when we talk about the English-speaking world, we're talking about all of these places where English is spoken by a majority of people. And that's why it's really important to learn and understand English because it's a widely spoken language that connects people from different parts of the world.
