* Official languages are used in government and official documents.
* National languages are generally understood to be languages spoken by a majority of the population, even if not officially recognized.
Here are Switzerland's four official languages:
1. German (spoken by about 63% of the population)
2. French (spoken by about 23% of the population)
3. Italian (spoken by about 8% of the population)
4. Romansh (spoken by less than 1% of the population, primarily in the canton of Graubünden)
Switzerland's linguistic diversity is a key part of its cultural identity and contributes to the country's unique character.
