Landessprache
Landessprache is a term used in German-speaking contexts to describe the language that is official or predominant in a country, a constituent state, or a region. It typically refers to the language used in government, administration, education, and public life, and it often reflects the language most widely spoken by the population. The exact status of a Landessprache can vary: in some cases it coincides with the official language designated by law (often labeled Amtssprache); in others it is a descriptive term for the language commonly used in public affairs, without formal legal status.
In multilingual states, there may be multiple Landessprachen. The designation can differ by level and region,
Common examples and usage vary by country. In many German-speaking countries, German serves as the primary Landessprache
