Every country in the world has at least one official language, even if it's not the only one spoken within its borders.
It's important to remember that:
* Official languages are languages recognized by the government for official purposes like education, legal documents, and government communication.
* National languages are languages that are widely spoken and considered to be representative of a country's identity.
* Most countries have multiple languages spoken within their borders, even if they only have one official language.
If you're interested in learning more about the languages spoken in a particular country, you can find information on the website of the country's government or a reputable language organization.
