And I'm Phil. And now that we've done our hellos, let's hear some greetings in different languages from around the world. But what do these languages have in common? Cassie. Dev. Devadeesh. Devadeesh. Jammaloma. Jain. Julainli. Vishabelle Kimakolalti Tej. I'm afraid I don't know what they have in common because I don't recognise认出 any of them.

We often hear about animals at risk风险 of extinction消失, but a recent study by the Australian National University found that out of the world 7,000 existing languages, half are under threat威胁.

But first, I have a question for you, Phil, and it's about a country which used to be one of the most linguistically rich places on Earth.
